I took my first pill of my birth control pack (Sprintec, generic for Ortho-Cyclein) but missed the second and third pill of the pack. I doubled up on the pills to make up for it as the instructions said. However, I didn't take this to heart and had unprotected sex throughout the following weeks, including the three days before that I would be ovulating had I not been on birth control. How much does this increase my chances of becoming pregnant? A lot, slightly, nothing to worry about? We'll be happy either way. Thanks :)

Also, since it was in the first week of the pack, does that increase the chances of me becoming pregnant or does that not have much to do with the outcome? Thanks for any help.

It depends how long you've been on the pill. If you've been on it for a while, your body is protected even if you miss one or two.

Nine months.

Although nothing is impossible, it is highly unlikely that you are pregnant. When you are on the pill, the hormones remain in your system for some time and it will take a while for your body to get back to it's natural state once you come off the pill (apparently you don't start ovulating properly for 6 months after you come off the pill).

I really wouldn't worry at all about this.
