Hi everyone. I'm sorry for everyone who's had a loss and those of you who are in that terrible limbo waiting for answers.
I wonder if anyone can help?
I had an mmc in April. I started bleeding at 6+5, though they thought it had happened at 5 weeks. With that pregnancy I had cramps from 11-14dpo that honestly felt like my body was trying it's hardest to have a period, except ironically I never cramp like that normally. It was 14dpo before I got a really faint bfp (Clearblue) followed by a similarly faint bfp on a frer (15dpo).
Fast forward a month and I'm in a similar situation. I'm lucky to be pregnant so soon after, but once again, a shadow of a bfp at 12dpo, and not much better today at 15dpo. I can barely see the bfp on a Clearblue rapid response even though I got 1-2 weeks on a Clearblue Digital. 
I had a cramp on Friday night (after the faint bfp) and then again last night. Both times they were prolonged and moderate. No spotting or bleeding as yet.
Obviously I'm convinced things are going the exact same way as last month and I'm either having a chemical or headed for another mmc.
Has anyone else experienced this? What turned out to be the issue? I'm wondering why I'm implanting late and whether that's the reason they're not sticking. Or if there's an issue with my uterine lining and/or progesterone?
