Labor? Should I call my ob?

Pam

Hi mommas so all day yesterday it felt like I had to go poop really bad and everytime I tried my lower stomach hurt and I couldn't go! And then I started to get light period like cramps and all night I had those cramps. Well I woke up this morning with the same cramps but now once in a while mainly when I stand I get a cramp that stops me in my tracks and I have to wait till its over. I tried timing them but doesn't seem like they are the same times? And sometimes my stomach doesn't get hard like a contraction? And sometimes it does! I also noticed bubbles coming out of my vagina and underwear becoming alittle wet? Is this all normal? I'm 37 weeks and 3 days. The hospital is an hr away and my fiance is at work so im not sure what I should do? Any opinions are greatly appreciated!
