Just updating again for anyone who stumbles upon this thread looking for information/similar experiences: I am in fact miscarrying. I went in yesterday at what would have been 6 weeks for an ultrasound and follow-up blood work and they couldn't even find the gestational sac (which they may or may not have seen two days earlier). This led to some alarm about it possibly being ectopic and since I had been having pains on one side and my hCG up to that point had been rising but not exactly doubling I was completely freaked out about this. They did my beta again though and numbers came back -- it dropped precipitously all the way down to 365 from 1500 something in just two days. As crazy as it sounds I was relieved to get this information for two reasons -- 1. It meant I didn't have an ectopic and that I was miscarrying naturally, and 2. It meant I finally had an answer and the anxiety and emotional roller coaster of the past few weeks was over with and we could move on to trying again. I started spotting less than an hour after we got the news. I had been on progesterone, though, so I believe I would have started spotting even earlier if I hadn't been supplementing.
I had a hunch something wasn't right about this pregnancy from the get-go and I never really allowed myself to get too attached to the idea of it as a result. I'm glad I let my intuition guide me in this case. I do believe in the power of positive thinking -- but I'm also pragmatic. This pregnancy wasn't viable from the start and deep down I knew it. My husband, mother, sister, grandmother and friend were all there to provide the rosy perspective and tell me everything would be ok and I was worrying for nothing -- which was great -- but next time I'll know to fully trust my gut.
Silver lining: This was our 7th cycle of trying and at least now I know I CAN get pregnant.
Thanks to everyone who responded with encouragement and/or support.
