I feel like a failure

Mery
Had a miscarriage a few years ago of our first baby and because of it I got scare I got in IUD and for years didn't feel ready to have a baby after that experience 😔 my husband and I talked and we agreed we both wanted to move forward that it was time for me to remove the IUD and try again but just when I decided I was ready ...I found out I have ITP which interferes with pregnancy and also means if I get pregnant I wil probably not get an epidural.... Despite the obstacles my husband and I still want to try but we have tried for a few months and nothing! now I'm getting to the point that when is time for my period to come I take pregnancy test before and get negative results and I feel like a failure as a woman because I havent been able to get pregnant ... Any advice? Anyone been through this that can offer advice as to how to cope with this?
