Birth control issue

I was off of birth control for about 2 months now. Not because I don’t wanna be on it but because I had switched methods so often and I started bleeding a lot. Now it seems my body has re-regulated. I’m going on vacation a month from today and I’m starting to spot which means next month I’m prob gonna have my period around the same time. Should I start my birth control so for then I can just push my period back a week?— will it be bad for my body? I know you can mess with birth control every now and then, and I never do but I really don’t want my period on vacation. I’ll be wearing a lot of white and it causes so many cramps and it’s heavy
