What are my chances?

Lindsey🌻🖤🔮
So I'm on the pill, which I take at the same exact time everyday. And this time when my bf and I had sex we used a spermicide foam and he came inside me. This was the first time we have ever done this and we wanted to be extra cautious, so I wanted to ask you guys what you think my chances of getting pregnant are! Thanks 😁
