Cd 17, Peak positive OPK, have BD less than 24 hours after +OPK? Pregnant?

TTC #1, My CD17 was my high peak positive ovulation day. 19 hours later we BD. There was some discharge after we BD.. I am afraid that all his ejaculation fluid came out. I lay down for 1 hour after BD. I wait 1 hour before urinating. when I went to the bathroom, there's this whitish ejaculation fluid looking, and when I wiped myself there was a scanty pinkish on the tissue. I was wondering if there was a high possibility that I could get pregnant. I am so worried that his fluid did not make it for I see some discharge after we had baby dance.. Anyone that can explain to me who is a little bit expert in the baby making?
