A little ouchy

I’m 38 weeks and 6 days. So I was tryna drive a moped which I have before perfectly fine just 2 weeks ago, but this one I tried to ride today was messed up and I wasn’t really aware. Anyways I started it and was tryna make it go but it wasn’t going so I stopped trying and I was just gonna give up but when I stopped it just started going on it’s own and wouldn’t stop and I ended up crashing into a pole, I fell on my butt and the moped was just on top of my legs and feet, no serious damage just scraped my foot a little and got a bruise on my leg. Baby is moving perfectly normally and everything is still intact everything is perfectly normal but now it just feels like a soreness balled up only on the right side of my lower back and very slight cramps but the cramps aren’t painful or anything I don’t know if it’s from the little crash cause it started happening like 2 hours after that whole situation but I won’t be trying to ride mopeds anymore any time soon.
