I am 25 yrs old. I was on the pill for 10 years but came off it 3 months ago as was making me ill. The first month I was 3 days late, the second month I was bang on time. This month I am 12 days late. I have always had regular periods so this seems strange. I did a test on day 8, 10 and 12 and all negative. I did them in the morning as is recommended. I don't think I have any pregnancy symptoms although have been feeling faint recently.

We have not using any contraception - just the 'withdrawal'method.

Is it likely I am pregnant or would it show up on a test now? Or is it likely to just be as a result of coming off the pill?

Thank you.
