confused and worried:(

Okay so about a little less than a week ago, I had sex with my boyfriend but the condom broke, so I took a plan b pill about 7-8 hours later. but last night we had sex again but he went in for literally like 15 seconds cause he didn't have a condom so we weren't gonna have full blown sex but he did finger me. when i got home i saw a little blood and this morning I look in my underwear and there's some blood again. im having period symptoms (boobs sore and some cramps) but I also haven't bled since this morning. I know that plan b messes up your cycle but I'm not due for another 12 days so I'm not sure if the plan b bumped up my period that much or if he just actually broke my hymen this time, is this normal orrr?://
