Hi everyone. My ? is this.

I had sex the 2nd day of my pd. The 1st day was normal. I kept the tampon inside of me and held the string when we had sex, and he finished in me. I figured the tampon would block or catch the sperm. Well after that incident my pd. stopped COMPLETLY. I only had it for 2 days. This has never happened before. Also this month my pd. was 2 days late. I am wondering could I be pregnant? Esp. if my egg did not release yet? I usually have my pd. an avg of 6 days.

Thanks!
