What's going on? BH?

So I work in a grocery store, all day today at work I didn't feel with it, like I was slightly light headed at work all day. I ate before work and definitely drank enough water, I drank two and a half big Dasani waters. I figured I'm just tried I've worked everyday last week with one or two 10 minute breaks, no lunch break, my work doesn't allow you a lunch break which yes I know is illegal. So yeah I figured I'm tired yesterday was my first day off in a week. As I keep going my legs keep taking turns going numb because she's on some nerve I think, this happens the whole 8 hours of my shift. Then all the sudden it feels like I'm peeing myself a little bit, so I freaked out and ran to the bathroom since I'm a hour and day away from being 36 weeks I was worried my water had broke. It wasn't my water, just A LOT of white discharge that came out. All the sudden my side starts cramping probably two hours after I checked myself. Which is nothing because I'm so far along and she's trying to make room in there. Also the roads are bad almost like a snow storm but not quite, so I'm stressing about having to drive home because we have this one spot that we spun out on last year when the weather was like this, it's a sharp turn. Turns out I didn't have to drive, my father picked me up from work instead. So we go home and my mom had diner almost ready and I start eating and my back and stomach and sides all start hurting and it's getting more intense, it stayed for about two hours. It would get to the point it was hard to breath because of how sharp the pains were. So finally I decided I'm going to take a nice warm bath, and it's finally stopped, I'm still in the tub as I'm writing this. But I want to know if this is Braxton hicks, my body preparing for labor? Or if it's because I'm so stressed. I have to get at least 40 hours every week to be approved for fmla leave. I've been declined once already. Because I was short 150 hours. What do you ladies think? The thing that gets my fiancé is that it really truly felt like I had peed myself a little bit, and I didn't even have to go pee. I can still feel baby moving a lot in there too.
