I can totally relate. After the 2nd BO m/c and being told that only after 3 they the fertility specialist would start tests, I was adamant I would go through another.
Then I became pregnant again. And diagnosed with Thyroid issues, maybe get your levels checked also.
We were so scared but went for scan at 6 weeks, by then I was already sure I was right (another BO) BUT sure enough a little heart was beating!
And now as I wrote this, breastfeeding my miracle!
Have hope and faith is all I can say. And it gets hard, as I wondered all the time while pregnant something going to happen (had 2 bleeds during ) and didn't really connect. I enjoyed being pregnant by the end. And even now it's still hard to not be over protective.
I wish you well and lots of sticky vibes!
