I need a second opinion

I posted this in another board but I need as much help as I can get. I’m about to start my period, here are the symptoms I’ve been having:

-VERY sore breasts

-mood swings/extra emotionally sensitive

-a few headaches (I also vape a lot so it could be from that)

-kidney pain/lower back pain

-fatigue

-pain when peeing

I put a picture below of my glow calendar with a key. I had unprotected sex with my boyfriend on the 17th and 18th, and then protected sex on the 19th and 24th. I’ve never had unprotected sex before, and he didn’t ejaculate inside of me, but he does have precum. However I’m on birth control, so i don’t know what the chances are that I could be pregnant. I haven’t felt sick or nauseas at all. Could someone please help?
