8 days late

Ma

Ok I’m 8 days late and I have gotten two negative tests. Kinda freaking out because my bf of a year broke up with me. We are freshmen in college. We had an accident with the condom during my ovulation period. I cannot sleep I just want to know for sure whether I’m pregnant or not. I’ve spent so much money on tests and two of them didn’t work (the control line didn’t even show up even though I was super careful and followed the instructions perfectly) this is stressing me out which is probably why my period is late but I have a lot of early pregnancy symptoms. Sore breasts, nauseous, tired, etc.
