Help me out

Laura

I had protected sex with condom on February 27 which is 3days after my period.When he finished it, he came on my body ( it’s not like pulling out), and I think a few drops touched my vagina lips, vulva. Could that get inside somehow? Normally, I have a regular 28 cycle period so my period has to come around on March 19 and I’m still not getting any period symptoms. Could I be pregnant?
