they say to take them 1-5 days before your missed period but i dont understand what the crap that means... Like how are you suposed to know BEFORE you miss your period?? just guess?
yeah its too early to tell. i think you should wait atleast 3 to 4 weeks after.
if you are not trying to get pregnant than i would suggest also getting Birth Control, dont count on condoms. (as you know, they rip) (and if it happens alot to you, that they tare and rip, i suggest getting better quality ones)
