So my last period was around the first of the month, it ended more or less around Nov 7, and recently my boyfriend of a year and I have been getting sloppy about protection during sex. On friday [Nov 16] we had intercourse WITH a condom, and saturday [Nov 17] we had unprotected intercourse, I am not on birth control. Last night was two days after the last time we had intercourse and I noticed a brown discharge when I used the restroom, I ignored it passing it off as nothing and this morning I woke up and there's still brown discharge, through out the day when I use the restroom I check and there's still some. A lot of sites are telling me I could possibly be pregnant, is there any other reason to this? Or is it a big chance that i'm pregnant? Please list any sites that are good to check out. Thanks!
