Hello, i need some help
Please. My girlfriend and I, were practicing safe sex. My condom as i ejaculated in her.

I was using a condom that had spermicide. I believe the condom broke right when i ejaculated.

We had sex on her last day of her period.

She took one pill (plan b) 30minutes after it.

I know nothing is 100% but are the chances very very low of her get pregant?
