UPDATE: Sorry I've been MIA
I haven't been on here at all since this... http://www.projectwedding.com/post/list/pretty-sure-i-m-m-c
So the 18th, I had been bleeding for a couple days at that point and I got home from clinicals and was leaving for work, and I just figured I should call the clinic where I had the appointment set up for that following Monday to confirm my (4!) BFPs to see what they'd say if I should wait to come in or not. When I told them what was going on they said to come in right away... Well, I got there and tey told me they didn't have the equipment to do an ultrasound and sent me to the ER instead. I called DH to come meet me there (he was at work). When I told them what was going on they had me take a urine test to confirm. The test came back negative and they sounded like they thought it may have been a FP, but I told them I had 4 BFP all different brands on different days and once the spotting started within a couple hours I could literally feel my pregnancy symptoms fading away (my boobs were no longer sore and swollen). I also took another test after the spotting started and the line took longer to show up and was more faded. I thought maybe that meant it was still detecting hcg levels but not as high (this was hte night before ER). After telling them about the 4 BFP they did a blood test and it was POSITVE! I knew I wasn't crazy, but the MD explained urine tests only detect hcg levels at least 50, blood detects the levels if there are any at all and mine were only 40. So it was positive, but not enough anymore to be picked up in a urine test. So anyway, that was my day a couple weeks ago. It all just happened so fast! We hadn't told anyone yet and were still wrapping our heads around it, and then it was gone so fast. :(
I've also heard of women being very fertile immediately after a MC, and I was worried about when my cycle would be back to normal so I started using my OPK after the bleeding completely stopped and surprisingly, I got a positive OPK on my 16th cycle day! I read somewhere that if you miscarry, you should count the first day of the bleeding as "AF". Not sure if this is true or not, but I did just to give me a timeframe idea and I got the positive C16, so who knows, but I'm thankful it seemed back to normal so soon... Not that my cycles are always consistent though. Before my BFP, I had cycles that varied from 30-41 days long! Sorry so long, jsut thought I'd share what ended up being the outcome.
