I would suggest taking a home pregnancy test.
You might be pregnant. I would buy a home pregnancy test, you can get them at the dollar store. Or you could go to planned parenthood and they could give you the test and birth control information.
Just took pregnancy test, came back negative. Been waiting for period to insert NuvaRing
It sounds like your not pregnant and it could just be the EC pill messing with your period.
Normally your body takes 3 monthss to adjust to new medication. After 3 months your period will be normal again
