I would say yeah, they want to make sure your progesterone is high enough to hold the baby in :) Congrats on the BFP :) that is wonderful!
I would go ahead and take it, and then call your doc and let them know that you are pg. It certainly wouldn't hurt to know what your prog level is at this point.
Congratulations!
Definitely do the test. If your progesteroe level is too low, you will need to take suppliments to have a healthy pregnancy. Congrats!
Thanks so much for the info! I will go for the test tomorrow, the lab opens at 7am!!! I'm so excited, we have been ttc for a year, and I had one m/c at 8 weeks.
