In need of a bit of help...

I’m taking pregacare and my boyfriend is on wellman we have been taking them for not even two months yet the start of August and that month of ovulation we had sex everyday and he cummed inside me and since then I have been bleeding two days before my actual period for about two or three days and then it would just slowly stop I should still be bleeding now as it’s last period day but I’m not the blood was a light spotting to start then got heavier like a period but it can’t be a period as I have a regular cycle of 28 days and normally I’m on bang on the day but I haven’t been twice in a row now

Did I going through a two or three day early period or was it implantation bleeding please help as I’m so confused right now and so is my boyfriend we keep thinking I’m pregnant now.
