I posted a question not too long ago about if 9 days after conceiving was good enough to confirm not pregnant with a period over a week late.. well the answers I got was yes and I'm sure they were right. Well anyway about 3 weeks after that happened I had sex, and after, for two days I had minor cramps, I thought my period was coming on but that couldn't be because it is nowhere near time for my period to come on. When I went in the bathroom to wipe there was light bleeding and times after that is was dark, u know the way it looks when your period is going off. It was like a very light 2 day period. This was two days ago and it has stopped. Should I still see a doctor about it?

Yes, I suggest to go see a doctor. Just to make sure what is happening. You wouldn't want to keep that waiting. You should go to your doctor soon so to find out what is really happening and to make sure your okay.
