Question

Hey, guys I’m new to this. So I recently started back up on my birth control pills. I started taking them on the 5th day of my period. Fast forwarding, I had sex and he cummed in me only after being on my birth control pills for 7 days. Immediately the next day around 12 in the afternoon I took a plan b. Now, it’s a week later and I’m getting sorta bad cramps like a period. Bleeding a light to medium flow. I am not due for my period until around the 23rd or 24th of July. I’m afraid that I might be pregnant.Any advice or something to calm my nerves !!!!! Thank you ❤️
