Cramping 33 weeks

This is my first pregnancy so I’m very new to all the feelings, so any advice is greatly appreciated.

I have been feeling pretty intense pressure in my lower stomach and pretty frequent squeezing and sharp sensations in my stomach for the last couple days, but with no real pattern. I also have pretty intense back cramping, however I have not really got any other symptoms of true labour. I’m just concerned because of the level of pain I am experiencing, even when I feel baby move it is causing me pain.

If anyone else has experienced this or has any advice I would appreciate it!
