Worried!

My boyfriend and I had sex Saturday night with a condom. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I was supposed to ovulate Sunday and Saturday I was supposed to have a 27% higher chance of get pregnant. He pulled out before he came and we both seen him ejaculate in the condom. After he came we looked at the condom while it was still on him and there was this white stuff around the base. Even though we watched him ejaculate in the condom Is this from me? We got emergency contraceptive the next morning and took it within 11 hours of having sex. We did the water test to make sure there were no holes and there weren’t any. Plus he pulled out before he came. Should we be okay? Or do you think we could be pregnant?
