Hi guys, I'm 18, my period started on the 22nd of April, (friday) and I started my YASMIN PILL. I've been taking it as I'm supposed to, but then on the Thursday, (28th) I had unprotected sex. I was scared as I heard that it takes 7 days till the pill kicks in fully, so on the night I took 4 yasmin pills, then 12 hours later, I took another 4. I had the common side effects people said would happen, and I had abdominal pains, headaches and a slight discharge as well. My pack is about to finish, and I am really scared as to what may happen! May I be pregnant? Or could something be wrong? Please help!!
