What is your experience with the "honeymoon" pill?

Savvy

I tried vitex and it helped my PMDD but now my period is a week late and now I'm "forecasted" to start my period right on my first ever cruise vacation :( Any advice? Should I try the honeymoon pill? I quit taking the vitex when it made my period late for 3 days, I'm just so bummed because it was truly working wonders for my mood and mental health. I'm trying to be positive and focus on the fact that it helped my awful pmdd but now I'm just upset about this
