Re: did you girls take any pills/etc before your wedding days???
Welcome to Health Fitness!!! :D
Regarding the pill... and what to do. Hmmm, here's my point of view.
Islamically, yes you are allowed to use contraception as you are just trying to delay getting pregnant. There are other technical things but this isn't the place to dicuss that.
Before getting married, it may be a good idea to get a physical exam done and discuss birth control options with your physician. Once you have all the options you can discuss with your fiance if you are comfortable. If not, then I'm sure you guys will figure something out when the time comes.
