I have had irregular periods for 3 years now and me and my boyfriend had sex and the condom broke. He didn't . What should I do? I was thinking about buying the Plan B and trying that.

The Plan B pill works up to 5 days after the incident. Read up on the side effects and any concerns before taking it.

You should start looking into a secondary birth control, also. Use condoms and the pill, for example. Or use condoms and an IUD or spermicide or both!

The point is, you can't be too careful. STDs and pregnancies can change people lives very quickly.

Be careful and take care of yourself.
