ladies what do you think?!?!

my husband and I had sex, he came in me but we used spermacide. chances of conception? im pretty sure I was ovulating. and he cums multiple times ALOT. I'm not stressing over it. he wants a baby but I haven't decided if I do or don't so it's not a big deal if I get pregnant. we typically use spermacide and that's it but I'm not usually ovulating when we do! and can his multiple orgasms dilute the foam? making it less affective...shrug. just really curious.
