Okay so I just got this app and I put in my last periods I remembered and I have had kinda irregular periods until like my last two cycles so apparently I’m supposed to start my period in 7 days but I had sex 5 days ago and I took plan b the next day I guess I’m just freaking out bc my friend told me plan b made her start the next day and another girl said It took her two months so when is the longest it took to get your period after taking plan b?
