5 weeks with pretty intense, consistent cramping

Hello ladies. I’m about 5w2d today with my first ever pregnancy. I know some cramping in the first trimester is normal, however I’ve been having some pretty intense, consistent cramps almost all day. They feel like my normal pre-AF cramps, which can get pretty bad. I am also mildly nauseated. No other symptoms, and no spotting as of now.

I haven’t even had my first GYN appt yet (scheduled for the 18th) so I’m not entirely sure who to ask, since I’m getting a tad worried.
