So last month I had to take plan B because i ended up having unprotected sex. I had a period a week after taking it(it lasted the normal 5 days and was moderate bleeding) and a week after the first period, i had another one on the 15th(normal moderate to heavy bleeding) and this occured durring my regular time on the dot.

Now im waiting on my period this month, it should happen on the 15th again, and am having major pms symptoms like sore breasts, nausea, cramps, headaches, moodswings and loss of appetite. I usually have these symptoms right before a period but I am still stressing.

Does plan b usually affect someone after a month of taking it?

Should I be concerned on why I'm feeling this way?
