I normally have a 4 - 5 days period. This month it was only two days and was heavy the first day and the second day it was light. It feels like movement in my lower abdomen and my breast has a tingly feeling. I had unprotected sex all the time without using any protection. Could I be pregnant?

If you had unprotected sex, of course you could be pregnant. However, it would be way too early to feel the baby move, so that fluttery feeling you have would be normal intestinal movement at this point.

If you bled, chances are slim that you are pregnant. Every once in a while we get an "off" period. One that's a little different from the norm. Have you taken a HPT yet? If not, do so using first morning urine.
