Someone help!!

My boyfriend got precum on the outside of me, (outer part of my vagina like where you shave under your belly) <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says I’m not ovulating yet, and this happened a day after my period ended. It did not get inside me and I took a shower immediately after, I know this sounds stupid but could I possibly get pregnant?

Update: it was not sex we were both just naked no penetration has ever occurred without a condom.
