Felt like i peed myself 😬

Jen • Mama to a beautiful baby girl. Henley Mae. 10.2.15
I was just standing at work and I felt like I peed myself. I went to the bathroom and noticed that even my shorts had a wet spot on the outside. I got freaked because it felt like a lot when I was standing there. It was enough to soak through. There was a little bit of mucus looking stuff on my undies and when I wiped. (Sorry) but not a lot. Any ideas? Or is this normal for being 38 weeks inÂ
