Is it all good?

so it was gettin steamy in the shower last night and we had sex without a rubber.

i was on my second day of my period with a “1% chance of pregnancy” rate on Glow (thought period sex is better in the shower as you might agree).

i made sure that he pulled out and came elsewhere away from me too. i am aware of pre-cum and all.

I also started taking birth control pills yesterday (I know that that has no effect yet for another 2 weeks but I’m more meaning that I’m on my way to taking extra precautions for future)

What are the chances that I’m all good and not gonna get pregnant just from that?

thank you
