HELP ME

Me & my SO had unprotected sex on the 8th or 9th . 7 days later (on the 15th) I started spotting ( ik it was spotting because it was light & 2 weeks before my period so)(never happened to me btw) but it stopped after a couple days (on the 18th or 19th) . I used boric acid suppositories for 2 days & the next day I started bleeding but it was heavier. I later found out that the boric acid causes vaginal bleeding . Ig what I’m wondering is could I be pregnant ?? I don’t have kids & I feel like I have a lot of pregnancy symptoms but that could be my mind playing tricks on me. HELP.

sb: my period isn’t due for 2 more days.
