Hi everyone,

I am on the pill but have recently been on Penicillin. I had sex 11 days ago when I was taking the Penicillin. I now know that the Penicillin could cancel out the effectivness of the pill.

I am due on my period in 4 days time. I have period pains but no bleeding as yet. I dont have any other symptoms of pregnancy.

What do you think the likeyhood of being pregnant is?

Thanks, SJ
