Ovulation| Pregnancy Question: if anyone can help that’d be great!

I had sex on my last day of ovulation and we used a condom. I got my period 15 days later for 6 days.

Can I still be pregnant?

Only reason I’m asking is because I’m having this weird pulses (not sure how to describe) in my lower abdomen top of my bikini line.

Has anyone experience this lil thumps/pulses?
