May be YES/may be no?

If you have had a period in the last month then the chances are you are not pregnant. Having said this I was 24 weeks gone when I found out I was pregnant. I had been having regular periods all the way through and I was on the pill. It turned out that the pill was inducing my monthly periods and if I had not been on the pill then my periods would have stopped just like with any other woman. Do a pregnancy test as soon as possible just to put your mind at rest, go and see your doctor whatever the result and I would also recommend using condoms as well as the pill for extra security.
