I need some insight (slight TMI)

My boyfriend and I are fairly young and still have a lot of life to live but I’m nervous I’m pregnant. I will be the first to admit he and I are not the safest, meaning we will go raw then he’ll put a condom on before finishing inside me, we have done this a lot more recently. To add we have sex around 4 times a week. I have been on birth control for over 6 years with the exception of the past month and a half, and that’s due to medical reasons, My doctor told me to discontinue it. I don’t know if I am but, my period is 7 days late, I am having horrible back pain, I am so nauseous to the point where I am in the floor. I have taken 3 tests and all I believe are negative. I’ll share a picture of them, but I would love some feedback, advice, or what ever you have to share. Thank you
