I don't think there is anything to prevent your period although they do have the Birth Control pill that makes you have only four periods a year and if you are going on the shot I know you have to wait until you get your period and once they give you your shot the blood flow usually goes away within a couple of hours! If none of this is a possibility for you theres always the shower or hot tub!!! GOOD LUCK!!!
Get Norethisterone - this is a progesterone pill that prevents the progesterone drop that triggers menstruation. You take this three times per day from three days before your period is due and continue to take the pills until you want your period to start, it normally starts within 24 hours.
You don't have to prevent or delay your period, just menstruate as normal. There's nothing that you can't do on your period and some things are even better on your period, such as sex! Get a menstrual cup so you can go all day without needing to worry about changing or leaking and you can enjoy things like swimming, then use softcups, diaphragms, or soft tampons for mess-free sex.

This doesn't seem to be a slang or idiom according to my search engine. A honeymoon is the period of time right after you are married, when everything seems wonderful and happy. Perhaps that is what the person meant.
