So I took a plan b back in mid-late May which caused me to have my period twice in that month. I got my period as scheduled in June but July (usually get my period the last week or so of the month) I didn’t get anything and it’s now August 6th and I’m 9 days late. I know the hormones within a plan b can throw your hormones out of wack and my period is already irregular to begin with so should I be worried? I had sex a couple more times after taking the plan b but it was protected.
