Are Headaches Normal in the Second Trimester

Headaches are common in the first trimester of pregnancy and may occasionally occur in the second trimester, but headaches in the second and third trimester could sometimes be a sign of preeclampsia, which is high blood pressure (hypertension) in pregnancy that could become a serious complication.
Asthma in Pregnancy

Experiencing an asthma attack during pregnancy may deprive the fetus of oxygen, so it's important to continue taking the asthma medication that you took before becoming pregnant, especially if your asthma was well controlled. Though it's impossible to predict how pregnancy may affect your asthma, it's important to note that your asthma can still be controlled during pregnancy.
Pregnancy, Bleeding

Bleeding during all phases of pregnancy may be dangerous, even though it can be caused by a large variety of factors. You should call your health care professional if you have any signs of vaginal bleeding during your pregnancy.
Ectopic Pregnancy

Ectopic pregnancy is a condition in which a pregnancy develops inside of a Fallopian tube or outside of a woman's uterus. Causes and risk factors for ectopic pregnancy include previous Fallopian tube infections (pelvic inflammatory disease, Chlamydia, gonorrhea), previous surgery to the abdomen, use of fertility medications, prior tubal pregnancy, and use of an IUD. Symptoms of ectopic pregnancy include pelvic pain and vaginal bleeding. If you suspect you have an ectopic pregnancy, medical care should be sought urgently.
How Much Weight Do You Gain During Pregnancy

When a woman gains too much weight during pregnancy, it can increase the risk of complications such as gestational diabetes, preeclampsia, and cesarean delivery. Healthy weight gain during pregnancy, which depends on pre-pregnancy Body Mass Index (BMI), however, can reduce the risk.
Is Extreme Fatigue Normal in the Third Trimester

While fatigue is a common and expected pregnancy symptom, extreme fatigue is not considered normal. Concerning causes of fatigue in pregnancy include gestational diabetes, anemia, thyroid problems, prenatal depression, and chronic fatigue syndrome.
Is It Normal to Have Back Pain in Early Pregnancy

As much as 70% of women experience back pain during pregnancy. While back pain is a common symptom in the second and third trimester, it is normal to experience it in the first trimester as well. Causes of pregnancy back pain include increased levels of the hormone relaxin (which loosens the body in preparation for childbirth), added weight, and others.
Ovarian Cancer Symptoms vs Pregnancy

The symptoms that can be common to both ovarian cancer and pregnancy are as follows: pelvic discomfort, abdominal swelling and/or bloating, urinary frequency, constipation, abnormalities in menstruation, nausea and vomiting and fatigue. Symptoms of pregnancy that are not usually seen in ovarian cancer are premenstrual syndrome (PMS), missed menstrual period, breast swelling and/or tenderness, weight gain and fetal development in the uterus.
Placenta Previa in Pregnancy

Placenta previa (also called low lying placenta) is a complication of pregnancy in which the placenta rests low in the uterus (womb) and covers all or part of the opening to the cervix. Causes include scarring, prior caesarian delivery, prior D&C procedure, and smoking, among other causes. The main symptom is bleeding. Treatment may include caesarian delivery.
PMS vs Pregnancy Symptoms and Signs

Premenstrual syndrome (PMS) is a variety of symptoms and signs that about 90% of women experience within the two weeks up to the start of her menstrual period. Pregnancy is the period in which a fetus develops in a woman's uterus, usually lasting about nine months (about 40 weeks). PMS and early pregnancy share symptoms and signs like mood changes, headaches, back pain, weight gain, breast pain or tenderness, and abdominal cramping. Some of the main differences between PMS and early pregnancy symptoms are the amount of vaginal bleeding, how long fatigue lasts, and the strength of the abdominal cramping. PMS symptoms that don't occur during pregnancy are joint pain and acne flare-ups. Moreover, PMS symptoms are fairly predictable. Early pregnancy symptoms and signs that do not occur with PMS are a vaginal discharge and darkening of the nipples. The only way to find out if you are pregnant is with a pregnancy test.
Pregnancy Loss

Pregnancy loss can be very painful for an expectant couple. Feelings of guilt, anger, and shock often occur. Learn how to cope the loss of a baby.
Pregnancy Planning

Pregnancy planning is important to help prevent exposure of the mother and fetus to potentially harmful medications and substances during the early days, and throughout the pregnancy. Nutritional planning, prevention of birth defects, conditions such as high blood pressure, heart disease, diabetes, and kidney disease need careful monitoring. Gestational diabetes, preeclampsia, and pregnancy-induced hypertension are conditions that may arise during pregnancy. Immunizations, inherited disorders, exercise, air travel, intercourse, and birth control are important factors to consider when planning a pregnancy.
Pregnancy Week by Week

Pregnancy occurs when an egg is fertilized by a sperm, grows inside a woman's uterus (womb), and develops into a baby. In humans, this process takes about 280 days.
Pregnancy, Round Ligament Pain

Many pregnant women experience abdominal pain for a number of reasons. Often, round ligment stretching is to blame. The round ligament is a muscle that holds the uterus in place, and it stretches as the fetus grows, causing pain. Treatment includes acetaminophen (Tylenol) and activity modification. Though round ligament pain is a completely natural an benign condition of pregnancy, other types of abdominal pain can indicate serious problems; seek medical care if symptoms become serious, for instance, if you have a fever, chills, painful urination or difficulty walking.
What Can You Take to Help You Sleep While Pregnant

Sleep medicines are advised against using during pregnancy, but there are other medicines and home remedies that can help you sleep. These include over-the-counter medicines (antihistamines), herbal remedies (ginseng, honey, nutmeg), melatonin, and prescription medications. Always check with your doctor first on what medications would be safe.
What Causes Hypertension in Pregnancy

Hypertension (high blood pressure) during pregnancy can potentially cause complications. Its cause is unknown, but risk factors include first-time pregnancy, previous preeclampsia, family history of preeclampsia, multiple pregnancy (twins, triplets, etc.), in vitro fertilization, type 1 or type 2 diabetes, obesity, chronic high blood pressure, chronic kidney disease, and others.
