Here's the story

 I had just came off my period for this month and I have irregular periods..

I had unprotected sex with my boyfriend  multiple times though out the day on June 6, And he came inside me but like he's really big for me so he hit the back of me ( my cervix) and it hurt .. 10 days later  I missed two days of my BC this month on accident because  They sent my pack late and I didn't get it till that Monday so I didn't take Sunday's pill.. All this time I've been having tender breast and getting sick ..  After I got my new pack and I took it I got my period but it was way to early !!!  It stopped 4 days later and I had a lot of clots .. Anyone know what might had happened ?  I'm no longer bleeding but now I'm throwing up and I have very tender breast and all I can do is sleep ..I have a doctors appt. in a week .. But can  anyone just give me some ideas on what might have happened?? ( sorry if I misspelled some things I just kinda want to get this over with ..)
