Random contractions all day?

b

I’ve been having contractions on and off all day... they aren’t regular but they are intense. I did have a cervical check today I am 1.5 centimeters dilated and 50% effaced I’m 35 weeks and 3 days. Wondering if anyone else is feeling these? I am also feeling him push down a lot. It’s freaking me out. This is my fourth baby if that makes a difference
