TTC Month 6

Me and my bf have been together 7yrs and while I just started TTC recently I had a pregnancy with twins 7yrs ago also where I went in labor early and they both passed and I feel as though my body can't hold a child😭 I had been scared to try before but now I'm even more nervous because for over a year now we have been having unprotected sex and I have yet to conceive  i have found myself so depressed and feeling lonely because every girl wants a child of their own and I feel that will never happen😢😢😢😢
