lol yes i think your mom is just trying to keep you away from the sex for now..Tri-Sprintec 28 actually is a birth control pill but you have to remember that even though its birth control its not 100% guarantee to prevent pregnancy
im using Junel right now and have had a few moments where i would have had sex too but the one thing that keeps me back from it is that its not 100% guaranteed so i guess i'll just wait til the time when i dont have parents to contradict and flip out if im not married to my bf and get preg. but you should take a pregnancy test just in case to make sure nothing is up =) there about 10 dollars for a pack of 3 at your local drug store..hope this helps
