Pregnant?

My bf and I had protected sex this May 1st and it was on a regular day of my cycle (one after my fertile ones ended) according to Glow. We made oral and a bit of sperm fell on the lower part of his stomach (like, above his penis) and then we hugged and kissed a little. After that, I sat on the lower part of his stomach (I didn't know there was sperm there, we noticided when it was already dry). Am I pregnant because of that?
