This Could Be The Start

So all day yesterday I was having bh contractions. They were pretty much non stop all day about 12-15 minutes apart but they didn't really hurt. At my doctor's appointment I was told that I was dilated 1-2 cm. Fast forward to about an hour ago- I woke up with intense pain in my butt back and vagina. Tmi but it kinda felt like I had to poop. So I go to the bathroom but nothing happens. I lie back down and dose off. It happens again. They've been every 9-10 minutes for the past hour and a half. On a scale of 1-10 they are probably a 7.  Hopefully they get closer and this is the real deal! Oh and I've started loosing my mucus plug.
