I am on birth control (mononessa) this is not my first time taking it. I took it the whole month of February I had a cycle on the 1st & the 25th of February. After I ran out out of the pack I stopped taking it for a while. I had sex it was protected I was off the pill & immediately I start back taking my birth control im still on the blue part. My cycle was suppose to came on the 23rd of March but it's a week late. When will I have my cycle or could it be possible that im pregnant?
