Birth control

My condom is expired.

I heard there's a risk in using tampons or a menstrual cup with the ring.

I had sex on the wrong day when using a fertility awareness method.

I’m breastfeeding and don’t want to be pregnant.

I heard that I don't need to use lube with condoms.

I've heard that EC might be less effective for me because I am using an enzyme inducer (such as Dilantin the antibiotics rifampicin or griseofulvin, or St. John's Wort).
