Just saying what other girls have said...
I like to take the pill so I don't have it for a big event. I'm on it regularly though, so it's not a big deal. Works like a charm!
Also, I ride with tampons and have had problems with irritation from the string, so just take care in where you place it. As long as I make sure the string is in a good position, no problems. On heavy days, I have bled through a little but with black shorts and a black chamois, it's not that big of a deal.
Also, stay hydrated, and maybe try to keep your iron content up. Seems that women are often low on iron during that time of a the month, so maybe purposely adding more to your diet would help.
Good luck! You definitely can ride, don't worry!
