I had one done at 8 weeks and will have to have it done again.
Yes maam. My doc actually had me do it couple weeks ago at 10 1/2 weeks. She said bcz i had it with my 1st pregnancy she wanted to see how my body was tolerating it this time. Thankfully it came back good, low in fact (go figure). said i still have to do another one around 20-22 weeks just to double check. I hope yours goes well!
