I have been spotting only when I wipe. I got off my period the 3rd of this month and started to spot when I wiped about 2-3 days after,did that on and off for a few days. Then after intercourse yesterday had a lot of bright red blood, and it turned into only spotting when I wipe after that and still is that way today. My period isn't due for 8 days. I've been having a lot of lower back pain and some slight cramping here and there. As well as headaches on and off which I never get.. and a lot of fatigue. Was yesterday's blood show and spotting implantation bleeding? Could I be pregnant? I thought all this was just hormones regulating after quitting breastfeeding. But I'm just not sure.
