Hi @Lisalou88. Sorry to hear about your miscarriages, life really can suck. 
I’ve had four miscarriages in total. One healthy son, first pregnancy followed by the four successive miscarriages at 10wks, 5wks, 6wks and 12wks. I am currently 35wks pregnant with what I hope is our rainbow.
I’ve had a range of tests over the course of the two years we experienced the miscarriage. Nothing was ever identified, and if I’m honest other than taking aspirin from 6wks, and refusing all vitamins, there has been nothing different done in this pregnancy. If anything we had given up and were at the point of moving on.
I’m 42 though, so much of what I’ve put it down to is a series of ‘bad eggs’. We finally got lucky with a good one.
Recurrent miscarriage is hard. Go easy on yourself. It can be all the more fraught with the lack of information or understanding as to what is causing it - seeking something to fix.
I found the focus of continually TTC as something that kept me going, and I think I would have struggled just ‘giving up’ - but the highs and lows were getting too much. After so many losses you also get a bit hardened, and a positive test becomes recognition that a baby will not always follow. Harsh, but a necessary protectionist mechanism.
Sorry, I’m rambling and probably not necessary helping you much. Just wanted to let you know, you are not alone. And there is hope. xox
