I had a period about a week after taking the morning after pill in early may
I'm normally on every 3 weeks (used to be 4 but =/)
now its been 4 weeks since that period
could the pill still affect even a few periods later?

Remember that the morning after pill is not always 100% effective. Might be time to try a pregnancy test.

I will I'm probably doing one 2moro
Just that I heard it can screw them up for several months?
Just wondering
