Patient discussion about trimester

Q. My daughter had lost her pregnancy in the second trimester. Something is going wrong with my daughter. She had lost her pregnancy in the second trimester. Something wrong was found in her ultrasound report. The situation was described as a molar pregnancy. After this miscarriage, still she is on regular examination. The very strange part is that they are still taking her hCG tests after her miscarriage. What sort of problem is this?

A. A molar pregnancy is a mass of tissue (hydatidiform mole) that forms an abnormal placenta inside the uterus. Even though it is not an embryo, a mole triggers symptoms of pregnancy. And the pregnancy test will result in positive value also. About 1 out of 1,000 women with early pregnancy symptoms has a molar pregnancy.

A molar pregnancy triggers the same first-trimester symptoms that a normal pregnancy does (a missed menstrual period, breast tenderness, fatigue, increased urination, morning sickness). It may be diagnosed during an early ultrasound test. In addition to normal pregnancy signs, a molar pregnancy usually causes additional symptoms, which can include:

Here are the most characteristic symptoms of a molar pregnancy :
Vaginal bleeding, a bigger size uterus that is abnormally large for the length of the pregnancy, severe nausea and vomiting, pelvic discomfort.

If you are diagnosed with a molar pregnancy, you will need immediate treatment to remove all molar growth fro

Q. I am in the final trimester and my whole stomach got really hard twice and hurt a lot. I am in the final trimester and from yesterday I am having extremely bad mental feeling and cramps and while at departmental store my whole stomach got really hard twice and hurt a lot....scared the hell out of me….it’s a heavy pain now, though I am relaxing now and still the pain seems to be arousing in a slow manner and I want to know what you all think?

A. Liam, since you're in your final trimester, be prepared to deliver your baby. I will suggest you to be more relax, and prepare yourself (physically, mentally, and emotionally) to deliver your baby at anytime.

Here I will share to you some real-labor symptoms :
- you will feel intensified contractions, it becomes stronger and more often
- the contraction will be more painful (that can feel like a cramp)
- you have bloody show (pinkish bloody streak from your down-there)
- you break the amniotic water

Okay, get prepared, and be ready to welcome your babyborn! Stay healthy always..

Q. My wife is pregnant and she is now in the first trimester. Her queasiness is disturbing her a lot. My wife is pregnant and she is now in the first trimester. Her queasiness is disturbing her a lot. She calls it as morning sickness. Almost all the day she feels nauseated whether she vomits or not. But every day she will throw once to have some relief for some time. I worry that this sickness can harm the baby. She does not want to meet the doctor as she says it’s normal with everyone who is pregnant. But I am worried can anyone give some advice?

A. my advice to you is the nausea and vomiting is a common thing that happens in first trimester. but be careful if the nausea and vomiting become more often and worse, by that time you must go to a doctor to find some help and therapy. it is called hyperemesis gravidarum.

so, make sure that what happened to your wife is in normal range, and good luck with her pregnancy! stay healthy always..
