What are the odds?

Storytime: I’ve been on the pill for about a year and a half. In that time, I never missed a single pill. That was until about 3 (maybe longer idk) weeks ago. I couldn’t get refills and missed 3 days, but took those pills as soon as I was able.

Even with the pill, my so and I almost ALWAYS use a condom because we’re both super anxious about getting pregnant.

What is the possibility of becoming pregnant in that time? How long does the pill stay in your system?

I know this is dumb, but like I said. We’re anxious.
