Periods and plan b

Stephany

Hi! So I’m going on vacay with my s/o on the 16-18 and I’m suppose to get my period supposedly on the 13th. I want to be able to get intimate but don’t want my period to interrupt. I know plan b had made my period come late in the past, I was thinking of taking it in the next couple of days in hope that it’ll delay my period but not sure how accurate that is. Can anyone help or have any ideas on what I could do?
