On the 11 of January i had my period as per usual, and it lasted 4 days. No problems there. On the 15, the day after my period was over, i had sex with my boyfriend and the condom had slipped off. Because there was semen in the condom, we weren't sure when it has slipped off and were unable to determine if the condom was on or off when he came.
Just to be safe, we got Plan B the next day, which i took around 3 PM (after work) according to what the pharmacist told me (save being maybe two hours off on my second pill, but i was told it doesn't majorly effect the outcome).
On the 18, my boyfriend and I has sex again, and, while i was lubed, he was quite rough with me. There was a little blood in my urine, but i didn't think too much of it.
So it is the 19th, and I am bleeding, with no idea if i am simply suffering from vaginal abrasion or if I'm spotting for a pregnancy.

I plan to purchase an EPT as soon as possible, but some advice, insight, and information would be nice!!

thanks!
