Are these contractions? FTM ..need insight please!

Al

FTM here...just got checked today- I'm 2cm dilated and 70% thinned. For the last week Ive had lots of pressure and being uncomfortable.

Well today since I've been checked I have had even more pressure and some straight up pain in my vagina area and lower belly and sometimes I even feel it in my butt(tmi) it eases up at times but then picks back up and hurts really bad again...almost to the point I have to stop what I'm doing and sit down. Now the pain is starting to radiate into my thighs...never done this before and I've always been told contractions will be in my belly but what the heck is going on down there?
