Weird cramps?

So I have been actively trying to get pregnant with my fiance and have been trying for the last few months well my last period ended about 5-6 days agos and just yesterday I started getting sharp to mild cramps over my pelvic area and I've never had anything like this before. I have to different apps that's track my period/ovulation. One says I ovulated a few days ago (and yes did have sex at least a day or to before that. ) And this one says I ovulated in two days and have had sex today. Is there a possibility I'm feeling symptoms from ovulation or conception/conceiving?
