A surprising BFP

Andrea • TTC baby #2 with PCOS
I'm so shocked I don't know where to begin.  Last month I did 50 mg clomid for the first time. I did not think I even ovulated because I had a follicle check on day 11 (early due to a holiday weekend) which showed no dominate follicle, never had a positive opk, and got a blood draw on cd 25 with progesterone at only 2.9 (above 10 indicates ovulation occurred).  I took a pregnancy test last week and it was negative so my doctor started me on prover 6 days ago.  I had just been feeling weird this past weekend and decided this morning I would take one last pregnancy test and was SHOCKED when it came back postivie. I am terrified to get excited.  This is so surreal.
