Hey so my period isn’t until 2 days from now , and I was wondering should I test.

Background story : before my fertile window had open me and my bf had unprotected sex and yes he finished in me , I can’t actually remember the days we did have sex . But we was having sex every other night where he did so cum in here ... then we were very active during my predicted ovulation.. and lil so afterwards. But once he did he told me to go pee..... so I searched and it still was a possibility of getting pregnant . The last time we had sex he finish off in me but didn’t let me know until after hours... I haven’t really noticed any symptoms other tiredness... terrrible lower back pain .. and nauseous but not actually throwing up ( like I’ll gag after a certain food I eat. ) and I be super hungry like starvingggg. Please help .. I don’t know what to do.
