Ok, so I started using birth control (Ortho Tri-cyclen lo)because I was going on a cruise and my period would start on the exact day that the cruise would start. Anyway, I took them for two months and I took the last pill last Friday. However, I had unprotected sex with my boyfriend on Saturday and Sunday because I thought I was on the pill, I didn't notice I had taken a placebo that day. He didn't come inside nor anything like that, but the thing is I was also taking ibuprofen and amoxicillin because I got my 4 wisdom teeth removed...I'm still taking amoxicillin. I knew that amoxicillin lowered the effectiveness of the pill but I wasn't aware that it was THAT much.
Anyway, my period hadn't come on Saturday, nor on Sunday nor on Monday. Now it's Tuesday and my period STILL hasn't come.
What could it mean? Could I be pregnant or is it normal for my period to be late?
