Mini rant very upset

My boyfriend has been fighting with me because I haven't wanted to have sex. Mind you I've been spotting all week and I've been so scared I'm gonna have a miscarriage. And all he cares about is sex sex sex and it's getting so annoying to me and I keep telling him he has no idea what I'm going through and he keeps saying well it isn't easy on me either and I do believe this change hasn't been that easy for him but I tell him the fact that you think you can compare what you're going through to what I'm going through blows my mind and that I wish he could trade places with me for a day. And that I've had to give up everything and the only thing he has had to sacrifice is sex and he is so selfish and I'm just so upset ugh!
