Little to no side effects after taking the morning after pill for the first time?

Well since most pregnancy tests won't tell you you're pregnant until you miss your period, you'll just have to wait. If your period doesn't come, wait about a week and if it still hasn't come THEN take a pregnancy test. The best results for one is if you do it on your first pee in the morning so it can tell easier before you put more fluids in your body. Also it normally takes 2 to 3 weeks for the sperm to attach to the egg and for the hormones to start sensing pregnancy. Just relax until then and don't think about it, because sometimes worrying about it can set off pregnant signals like missed period, nausea, but you won't be pregnant, you're body will think it is cause your stressed. Hope this helped!
