Another "is this labour"-question, sorry!

So I'm having weird contractions since yesterday evening (it is 2pm over here now).

My belly gets hard and there is a lot of pressure down there. Sometimes there are menstrual like pains and pains in my back.

A hot shower did not help.

I thought, if these are real contractions, they have to get worse after some hours, right? 🤔 Unfortunately I would need to go to the hospital to get checked, if that is needed and I would like to avoid that as long as possible..

I know you are no doctors but I can't ask anyone else..

So if these are real contractions or at least some that could get real, how can I help things along?
