Am I pregnant (I hope not)

I have been having sex a lot and we use condoms all the time ... I can’t take birth control for medical reasons. The condom has fell off about twice... and we had sex once without the condom but he pulled out... what makes me think I might be pregnant is that my boobs have been so sore ... like ridiculously sore and I have been getting headaches more than normal and I am also very tired and my body is like aching .. this could be from my job schedule changing and me now working 6 days but that doesn’t explain my boobs being sore. Like any slight touch feels sore .. I don’t want to get ahead of myself because I gotta wait another week for my period ... I just want insight
