Possible Miscarriage or Irregular Bleeding?

So about two weeks ago, I bled a tiny bit after my husband and I had sex. Well, I’m not due for my period for another two weeks and I started to bleed. I had cramps and I have been a little emotional lately. It only lasted two days. I’m pretty regular with my period, but I’m curious to know if this has happened to any other ladies. I’m a bit concerned. There weren’t any clots.
