UPDATE I always think I'm in labor!

Lauren • Currently pregnant with baby #2!!
UDATE: went in to get checked because my doc suggested it. I'm 5cm but stopped progressing and got sent home. The disappointment is intense. Still having contractions though so there's hope. We will see. 
Okay so last night I had sex... and this morning... haha. I've been having contractions since 10am. It's now almost 3pm. They started out about 5min apart (this happens every time I have sex) and then moved to about 10-15min apart and they've been that way since about 12pm. They're painful. I can still walk and talk through them but they definitely hurt. And it's a lot in my lower back. I've hardly felt baby girl move since about 11am. I took a walk at about 2pm to try to see if it would stop... it didn't lol. And I've been really active all day nesting and then went to lunch with my sister. I just don't know what to think. I kinda wanna call my doc to see what she wants me to do. But at the same time, I've been disappointed twice with false labor. So idk!! With my first they broke my water to induce me so I don't know what going into labor on my own feels like. I've also had diarrhea for the past 3 days including today. And lost my mucus plug on 04/01. Any advice?
