I had unprotected sex 4 days before my period (which was yesterday) I was wondering if i could be pregnant? my cycle is normally 31 days but my period was on the 9th of december, and the one before that was on the 7th of november, and the one before that was on the 9th of october........see a pattern? so i don't know what it will be this month, but i am going by last month so it should start on the 9th of this month unless it follows that pattern and begins on the 7th. anyway, if i am pregnant will i still bleed atlest this month?
