Bleeeeeding

I have been bleeding for 2 weeks (13 days to be exact) and IDK WHY!!! My periods usually last 6 days . My son is 7 months old and I’ve had 2 regular periods. But I literally won’t stop. It’s get light like it’s going away then it’s right back heavy

I feel like I shoooould add about a month ago I was on meds for bacterial vaginosos -found out my boyfriend had been cheating on me the whole time, idk could it be from him throwing my ph off again and my body just working harder to clean ???? (He has been out the picture for about a week now 🥰😊)
