I have been on birth control pills for this entire month. However, I am not entirely sure if I am pregnant or not..

I've had unprotected sex with my boyfriend an entire 10 days or more after retaining usage of the pill. But, on 4th of july, I had unprotected sex with him, but did not take my pill that night because I did not bring them with me... But I did double up the next night.

Apart from that, I had to take plan b, the morning after pill, a week or so prior to that incident because I did not wait 7-10 days after usage of the pill to have unprotected sex.

During that episode, I went to a planned parenthood clinic to obtain the pills because I was at risk for pregnancy. That same day, since I already had the pills, I had unprotected sex again, and took the pills that same exact night.

I missed my period and am currently on my green "sugar" pills. It has been 2 days and I still have not had my period. Plan b says it can delay a menstuation cycle for approximately 7 days, but are there possibilities that I am pregnant?
