Could I be Pregnant?

So, I am happily married and financially stable. I know if I am pregnant it’ll be a BLESSING from the good Lord above.

However, I am also just 20 and would like to keep learning my husband and enjoy one another while building a quality life for our future family.

I am on birth control; although, I LOVE my man cumming inside of me. Oh my goodness, just thinking about it makes me all hot & bothered haha.

Considering birth control is 99% effective, does that effectiveness change when your man cums in you, or does the percentage remain consistent? As in, do certain factors change the chance? Or, no matter if he cums in your or not, does it remain 99% effective?

I’m mainly just curious haha. Thank you for the answers in advance from all you wonderful people!
