This is the "Am I Pregnant" forum so she does have the right to ask if she may be pregnant or not. It's not a forum just for women that are already pregnant.
It might be too early for the potency test since your period isn't late though
You should take a pregnancy test. You could be pregnant or the pill just threw your body off.
I've never used plan b, so I'm not sure about the discharge. However, I have heard that it can change your cycle. If you are going to be sexually active, you should go to the Dr to get birth control. They will give you a pregnancy test to make sure you aren't. Also, if you are stressed out about this your period can also be late so just relax. :) & use protection lol good luck
No offense but this isn't a forum for women who don't want to be pregnant. Idk why you would think any women on here would know anything about the plan b stuff. We're all having babies lol
