I’m crazy

So I’m literally crazy.... my baby fever and craving to be pregnant is off the charts nuts. Last year I had a miscarriage and ever since then I haven’t been able to control myself with wanting a baby. I think about it every day and I’ve been trying and trying to get pregnant but I don’t know what I’m doing wrong. I know I forgot to log my period last month so I have no idea when to expect my period to come even though I don’t want it at all. I feel insane, I get so upset because I’m not pregnant, everyday I just ask to be pregnant and knowing I’m not just makes me really depressed...
