Preterm labor?

Getting straight to the point here. 2 days ago baby dropped (I’m a ftm so I know this doesn’t really mean anything as it can happen weeks before delivery) all day today I have as period cramps (since 10 am and it is now almost 5pm) they have not stopped and the only pattern I’ve noticed with them is that they come about every 20-30 minutes and they HURT. Lower back pain and after every cramp baby moves like crazy (she also move occasionally through a cramp but mainly after)

Don’t feel any “pressure” other than in my hips because it feels like she is stretching.

She has not stopped moving except for about 10 minutes here and there which is odd she is going absolutely crazy in there.

I have an appointment tomorrow with my OB at 5PM but I cannot sleep with these cramps (I tried to nap earlier and woke up about 4 times from the cramps) and vagina gets that period cramp feeling as well.

Should I go to the hospital or try to ride it out until tomorrow afternoon. I am 30w1d
