Bleeding

Hunter • Full time college student on top of emotional wreck once a month
Okay... So I've been taking my bill same time everyday like I'm supposed to (I have an alarm on my phone, laptop, and whether I'm with my SO or not he always reminds me) I would understand why this was happening if I took it randomly but I'm not. So I had my period the normal time (3 weeks ago) and I finished was fine for two days and BAM bleeding & cramps. That went on for a week and then it happened again and stopped and I had sex with my man today went to "clean up" and I'm COVERED in blood. Should I freak out or just go to the DR. Calmly???
