Help!!

So my fiance and I had protected sex today. We took off the condom and hopped in the shower together. There things got hot and I was on my knees giving him some oral. He ended up cumming down my chest and it may or may not have washed down my body. My concern is that it may have washed down my body near my vaginal opening. I am 3 days past ovulation and Glow says I have low fertility. Should I be panicked about being pregnant?
