Delaying period for wedding/honeymoon

Megan • mama to q + p 💗💙
I'm worried that I'll be on my period for my wedding and honeymoon. I want to delay it using birth control but I'm not on bc right now. I have an appointment with my ob on April 22 and hoping to start bc then. Is that enough time to get my body adjusted to bc and to be able to delay my period for my August 6 wedding and honeymoon right after?
