Feeling low 😔

My fiancé and I have been trying to have a baby for over 8 months now. I know that it can take a healthy couple years to conceive, I'm just really struggling with that. I also recently found out that I have factor v. (For anyone who doesn't know, factor v is a blood clotting disorder. It can cause recurrent miscarriages and difficulty with pregnancy). We've already had one miscarriage and I feel like it's my fault. Like I'm not going to be able to have a baby. It hasn't caused any true issues between us because he's amazing and very understanding. It just gets hard to see everyone around me getting pregnant so easily and having beautiful babies and we're struggling so much. Sorry for the long rant I just needed to get that off my chest and I feel bad when I bring it up again to him whenever it starts to stress me out cause I don't want to make him feel bad too.
