I have had the morning after pill, a week or so after I had a period however I haven't yet had my regular period. Could I be pregnant?

It is possible, although unlikely if you took the morning after pill in the right time frame.

The morning after pill can mess up your cycle pretty bad, you can experience bleeding, spotting or a delayed period. It's different for each person.

After reading your other post it may pay to hold off starting your pill until you have had a period.

Good that helps a lot with that then. It's probably just a little late, I only had the morning after pill round about 3 weeks ago though, if I get a period soon should I start the pill then or wait until my next on? but as they are irregular I don't know when it will be. X
