I've been having so much sex but I am not pregnant 😔

I just don't understand this has been my 12 month I believe an it seems like every time I get my hopes up my stupid period shows up like what I'm on right now I'm going to a ob gyn on Monday but it just doesn't make sense as to how many times my partner has came in me we have done it like mostly every single day or every other day and I am not even pregnant like wtf😒
