What are the chances?

Hi!

I've been on Alesse for 6 years now. I've never had problems with it.

Last Friday I was meant to start a new pack of pills (I had my periods from Feb 20th to 23rd, very light but normal). I forgot to take my 1st pill on Friday night so I took it right away on Saturday morning around 8h30 when I realized. Then I took my 2nd pill on Saturday night at 9pm as my normal schedule. I haven't missed a pill this week, always at 9pm.

Last night (Thursday March 1st) I had unprotected sex. It was with my boyfriend, we usually always use condoms as added protection. In the heat of the moment yesterday, we didn't.

Only this morning, did it hit me that I'd taken my very 1st pill of my new pack 12 hours late.

What are the chances I could get pregnant from this?

It's happened before that I forgot pills but it was well over 7 days in my pack. It's happened before that I had unprotected sex and I've never been pregnant or had any kind of scare.

Guess I'm just looking for re-assurance? Thanks!

You're right that starting your pack late is one of the riskiest mistakes in taking hormonal birth control. However, it's by no means a guarantee that you will ovulate. Some people who stop taking birth control in order to become pregnant find that it takes a few months before they ovulate again. Studies suggest that it probably takes at least 10 days (so three days late on a 21/7 pill like Alesse) before ovulation is likely.

This paper has a chart comparing different pill-free intervals: http://apps.who.int/rhl/fertility/contraception/Contraception%20series%20Curtis_SPR1_06.pdf

Most guidelines suggest you don't need to use backup in your case, since you made the pill up. No method of birth control is 100% effective, and you're not at perfect use, but you still have pretty good protection.
