1) Two condoms work better than one.
This is false because they actually increase the risk of pregnancy and STDs. This is because the friction that occurs causes small tears and/or holes in the condoms allowing sperm to get out and making them ineffective.
2) If you pee right after sex, you won't get pregnant.
This does not work due to the fact that the tube that girls urinate out of is a different one than the vagina. Therefore, the pee cannot wash out the sperm, because it is not even in the same tube as the sperm. Urinating after sex may be helpful in the prevention of urinary tract infections, but NOT in prevention of pregnancy.
3) You can't get pregnant before your first period.
You can become pregnant because ovulation, or the release of an egg, may start up to two years before she actually begins her period.
