I took myself off birth control about two months ago and have been using condoms every since. My husband and I went camping and forgot the condoms so had unprotected sex two days in a row but pulled out both times. I was suppose to start my period a few days after this. I started out with brown discharge for about 3 days and then it turned in to red and a regular period. The first day was heavy and then the second day slowed right down and now on the 3rd day is pretty much gone. So was this my period or could I be pregnant? Also my periods have always lasted 5-7 days, and usually I never ever get cramps but this time I did.
