I am 16 and half weeks pregnant And was told yesterday at the Dr that my baby might have Trisomy 18 but they dont know for sure yet. because i havent had a amnio.But the dr I seen was not my actual dr. It was at a different hospital . But they said we where gonna lose our baby just from looking at the ultrasound. But ever since I have been pregnant i have had brown vaginal discharge which my dr says is normal and fine. But ever since yesterday after i went to the dr I have had the same light brown discharge but its now a light pink with clumps or chunks in it. When they said i was gonna lose the baby they said they didnt know when or how.But yesterday our baby was moving around like crazy on the screen and the heart rate was 153 and its been around that since ive been pregnant. But I was just worried after having the light pink discharge with clump or chunks. what that might be???? I havent had any cramps or pains or anything tho. But yesterday when they did the ultrasound they did a vaginal ultrasound. And I didnt know if maybe the light pink chunks where maybe the lining of my uterus or maybe dead skin cells or something and when they did the vagnial ultrasound it maybe knocked some of the dead skin cells or lining lose or something. Any info for me????

### output:

Hi there,Please do not be so tensed, having been told that you are going to lose your baby must be a devastating experience. But nothing is confirmed till a definitive test such as an amniocentesis is done. A transvaginal ultrasound does not cause any damage to the lining of the uterus or to the pregnancy, do not be very concerned about it causing harm. If some defects were identified on the ultrasound we will need to rule if they are isolated or associated with a genetic cause such as a trisomy. The amniocentesis will take some fluid from around the baby and analyze it for the DNA. But if the baby does have a genetic defect it is also more likely to miscarry itself, which could be a cause of the constant mild spotting you have already had through this pregnancy. If the amniocentesis comes out with a normal finding and there are still defects observed on the ultrasound, you will need to get detailed scans at 20 weeks and a cardiac ECHO of the baby at 22-24 weeks to rule out other problems if any. Hope this helps. Regards.
