Hi doctor,

My wife is currently 6 weeks pregnant. On USG the following have been found:

Uterus is bulky. Well formed gestational sac with a living embryo is there. Yolk sac is seen.

CRL= 196.8 inches

Heart rate of embryo 121 bpm

Ovaries are normal in size.

As prescribed by the doctor, she is taking Duphaston thrice a day, Folic acid tablet once a day and Normozyme syrup twice daily. She is weighing 134 lbs and her age is 27 years. I want to know whether everything is alright? And what does bulky uterus mean? Will it harmful for the embryo? She had an anembryonic pregnancy eight months ago and had undergone D and C. We are very much tensed as well as excited. Please suggest.



Welcome to

I see everything is absolutely fine, nothing to worry about.

When the baby comes into the uterus, the mother's body has a lot of changes, most important is the excessive blood flow throughout the body. This is required as the baby is a fast growing life. It needs a lot of energy to grow. When blood flow to the uterus increases, the size increases. This is just the beginning. The non-pregnant uterus is only 2.7 inches long (length of your finger), which has to reach the level of her heart almost. Blood flow everywhere increases face blushes, redness of skin all over, excessive discharge from nose, mouth, stomach and so on as blood flow to these glands increases. Six weeks is the earliest baby heartbeat is seen, so you do see a good sign. Yolk sac (energy store for baby is seen) is a good sign. Well formed sac means no bleeding and the attachment to the uterus is healthy. All the signs are good. She is on supportive medicines. Her age is perfect for pregnancy (19-35 years is a good time).

About the anembryonic previous pregnancy, it is due to a genetic abnormality. The best sperm meets the best egg at the right time and sits in the best place in the uterus to form the best baby. Any step wrong in this leads to a bad baby. When you see baby's heartbeat, it means baby is genetically normal. So do not worry about the past. Such abnormal pregnancies are accidents, but accidents do not occur every time. The journey of pregnancy 40 weeks is a long one. There may be problems (every pregnancy can have) but have faith in God, follow doctor's orders and hope for a healthy baby and mother, at the end should be your expectation. Do not think anything that happens is a bad sign. Positive thinking will allay your anxiety.
