Okay so I need help I had sex (withdrawal method ) last week on a Tuesday I was supposed to get my period the next day but I didn’t get it but then on Thursday I started to bleed a little but this blood was like a brownish color and there wasn’t that much of this so then comes Saturday and I started to get normal red color blood so it changed from brown to red and I thought I got my period but it’s very very very light I bleed a few drops like maybe 10 and I change as if it was a normal period and I’m still having this happen since last weekend and since I’ve been bleeding it’s been 8 days and idk what is going on.
