Hi, I had unprotected sex on Wednesday 4th and was becoming fertile on Friday 6th and ovulating on Monday 9th. The last few days I had cramps and started to bleed like my period and its quite red and its like a medium flow. But I am not due until April 23rd. I have never been early for my period either. Either on time or a few days late. Could it be implantation bleeding or period because I'm really worried and never been pregnant. It be a great help. Thank you.

Last Monday I notice brownish spot in my underwear, when I wiped myself it was light pink color. I had some cramping pain and I was very moody. I also notice on Saturday the same with cramping. My next period should be came April 25 and my last period was March 24. My periods are regulars, but almost three months ago I had a baby too, I being having sex every other day. What this bleeding spot can be, And Should I worry about it?
