Thanks...And long time no talk

Last time I chatted with you was a little over 3 years ago. Before I had my first baby
Good for you for still being here!
I became Hypothyroid after my second baby...could that be it?
Also, I think I may have lost a baby. I had SUCH a late period. I blood tested at HcG level 2 and then again a few weeks later at nothing, and then got the brown...then today I had INTENSE pain and there was a small grey thing (looked very fetal) with an actual cord hanging from it. And I've been bleeding SO much. But now the pain is just normal period pain.
I dunno though.
Thanks for letting me know what it can mean!
