1st mc complete no intervention needed.
2nd mc complex, d&c then they discovered another embryo ectopic and I had surgery for that too.
At that point I got a dx of endo, yet more surgery plus medical management.
But even with the endo dx I decided to do some research of my own. Off the back of that research I chose to quit caffeine, alcohol and avoid as many food additives as possible and stopped high impact exercise as soon as I was ttc again.
I'll be accused of scaremongering probably, have been before, but I wasn't taking any chances. I can't know if that was what worked or if it was the endo treatment or a combination, or not, but the next pregnancy was successful and I got dd.
Unfortunately separate medical issues meant I couldn't have any more children.
It's incredibly tough going through mc, I have a relative and a few friends who had way worse times than me and never found out why, probably unknown genetic issues.
Although one of those it was anti phospholipid syndrome and I was appalled that she wasn't dx until she emigrated to a supposedly less developed country where they dx and treated it quickly and easily and she then had her lovely children.
I found the mc association very supportive and informative as was the endometriosis Uk.
I wish you so much luck in having a successful pregnancy
