So I just took plan B earlier today like a few hours after my boyfriend and I had unprotected sex, it was a just woke up quickie lol. This is the first time I've taken it. So I have a few questions; I'm supposed to get my period in 6 days and on the label it said the pill could make my period early or late, so which is more likely? I get it in a few days or a week or 2 late? I also read some girls saying they got really bad cramps, am I okay to take pain reliever if I get cramps? Should I be good to drive tomorrow, right now I feel dizzy, does it go away after sleep or does it happen for a few days? How long do the symptoms last? Does my period go back to normal next month or does it take awhile to get back on track, like does it go back to being a consistent pattern or randomly occur each month for awhile?
