TMI but need to know if this is a sign of labor

last night I noticed a bad sting like papercuts on my vagina and looked to see if it was cut anywhere from trying to shave. there was no cuts but all around the opening was very puffy, not red or anything. just super soft and looked like it was 3 times the size it normally was. this morning I was still puffy, not stinging tho, and my vagina was completely opened, and it looked like all my insides were trying to come out the opening. I have felt mild contractions fairly spaced out for a few hours and have a bad pressure that feels like someone trying to have sex with me but from the inside on both my vagina and my butt. I've also been going #2 just about as much as #1, normal looking #2, and have had a lightish brown mucus or a green mucus all weekend and it's a huge amount. every time I wipe, often in my panties, and even when I touch to feel if I'm still puffy, I get huge strings of it.
