Ladies help!!

This is my 4th baby first three were girls this is my first boy. I’m currently 34W&1D but measuring 2 weeks ahead so 36W this is my first complete breech baby he refuses to flip with my first 3 I had them all in the 37th week. Lately I’ve been feeling sooo much pressure and period cramps like that first day you get your period where u want to curl up in ball type and because he is breech I will most likely need a c section (never had one) I’ve just been so out of it these past couple days should I be worried labor is really close for me?!
