Worry-less sex

I just started a new packet of birth control. I haven't taken this stuff in years!!

My ex was all about condoms so we never had any issues. My bf today however hates condoms and I finally decided to take the pills since I'm scared of everything else. 🙈

My question is how soon can we start having sex, without having to worry about a baby coming around the mountain.

Thanks ladies, much appreciated 🙏🏽
