Can I be pregnant ?
There is a warning on the package that they are not guaranteed to be 100 percent effective....and so, yes.
ANYTIME you have sex it is possible to get pregnant. The egg and sperm DO NOT read calendars. Did you get pregnant this time? Probably not..
Yes. Condoms are not the most effective form of birth control. Birth control pills are. If you are going to continue to have sex on your fertile days, and you don't want to become pregnant, get on the pill.
