Contractions

FTM, I have been having lots of pressure contractions, makes me nauseous and makes it hard to breathe but I can still breathe through them. Not period like pain or sharp. Just lots of pressure. Are they BH or the real thing? I am timing them and they seem to be irregular but within 10 minutes apart and it doesn’t matter if I change positions or stay still, drink water or not. They just keep on coming. It’s been inconsistently on and off since yesterday.
