Hey Everyone! I've been lurking around this website for a little while now and it's just great. I actually feel comfortable asking my question here. I looked in the memories and didn't see anything about my question really in there. Sorry if it is though! Anyway, recently I was asking to go on a cruise early next year. I counted out all the months to see if I would be having my period at the time of the cruise, because, well that would suck. hehe. Well, of course I will be having it at that time. I was able to calculate it because I'm on the pill and I get it exactly every 29 days. So anyway, my question is, is there anyway to change the time that I will be getting my period so that I don't have to worry about it while on vacation? Like change the time I take my pill or something? It would be easier if I wasn't so scared to use tampons so I could still go swimming and stuff, but I am. I know that the time could change and I won't get it while on vacation, but I want to be prepared. Sorry this is so long, and thanks in advance for any replies!
