Help glow moms!!

Deyona
So I know what lighting crotch feels like. And have been having it more often now that I'm 39 weeks and 3 days. 
But I also feel like I'm having some camping, similar to what pre-period cramps feel like. 
My question is, how can I tell the difference between the two? 
Sometimes when I feel like I'm cramping, I have the urge to go number 2 in the potty. But don't actually have to go. 
Other times it's just a quick Jolt of pain ( I'm assuming is lighting crotch) my due date is the 12th of this month and my last doctors appointment I was 50% -60%effaced with no dilation. 
I'm a FTM so this is all new to me. I'm not spotting and I haven't lost my plug yet. My next appointment isn't until the 11th. So any help or advice or information would be great. 
I'm worried im not progressing like I should?
