Hi,
I've been taking combined birth control for about 4-5 months. I had sex without a condom with my boyfriend about 5 weeks ago. I went to the bathroom afterwards and a lot of it came out. I take all of my pills at the same minute everyday. I have never missed a pill. I don't take any other medications and antibiotics. I got my period. But I am still concerned about being pregnant for the following reasons:

1. It's my first time having sex without a condom so I don't know what to expect.
2. I know the period I get on birth control is fake, and that many people still get a period on bc when pregnant.

I am just very worried. I take levonorgestrel and ethinyl estradiol combined pills.

Thank you for your time
