I don’t know if I’m pregnant

Hi guys so like a week ago I had protected sex for the first time with my boyfriend and he didn’t come in me but we did do it a bunch just so I could get used to him being inside me. Every time we used a condom and he would finish after. Oh and I am not taking birth control pills. However I’ve been having a little pain on my left breast and I’ve been eating so much and I wake up every morning thinking I might be pregnant. I’m supposed to get my period in a week so idk if these symptoms are for that. This is my first time and I may not even be pregnant but i am super paranoid and scared. Someone please tell me Something and if they’ve been through something like this too. Thank you
