labor? 38 wks 3 days

Morgan • Army Wife 💏 Expecting our Rainbow baby 🌈🤰🏼

so for the last two days my back has been feeling like I'm going to start my period also I have been having the pressure of ending to use the restroom but no luck. as I'm on my way to take a bath to help with my back I felt as if I pee'd a little in my undies. As I wipe its alot more with a yellow tint slight odor but not like pee. I'm 38wks 3 days and I about to go into labor or is this all normal. first time mom after 2 missed miscarriages.
