Could I be pregnant?

So basically, my bf and I aren’t “trying to conceive”, but we definitely aren’t trying not to. We’re kind of just letting nature do its thing lol. We stopped using protection and he doesn’t pull out either and hasn’t in a month or 2. The last several months I’ve been getting my period exactly the day I was supposed to. Last month my boobs were hurting way more than usual and I didn’t get any cramps so I was going crazy taking tests for the days before my period but ended up just getting it when I was supposed to. This month I just put the possibility of being pregnant out of my mind; I’ve been worrying about other stuff and just enjoying my life. I took a test the day before my period was supposed to happen and it was negative. The past week my boobs have been sooooo sore, and I’ve been getting headaches and light cramping. I’m about 4 days late on my period now and I want to retest but I’m scared to 🥺 what to y’all think?
