Someone please Help

I'm ovulating today which I know because I got a postive last night around 1am and today my ovaries hurt really bad. My husband and I had sex last night in which he didn't cum but said felt like a little bit of something came out not a full release. Can we still get pregnant or is the chance so slim I should just count myself out. We can't have sex anymore this week as my husband has a tooth ache which is why he didn't cum last night.
