Pregnant after Miscarriage

Right now I am 3 weeks late but I can't bring myself to buy a pregnancy test after I misscarried at 8 weeks in February. I don't even want to know if I am until I'm at least 8 weeks and neither does my SO. But in my head I feel like this is real again but we're just too scared to think it could be true or that i could lose it again. How long do y'all think I should wait/ or am I crazy.
