26 weeks Braxton hicks?

Well I had a arguement and my stomach clenched up and I think I peed myself a lil bit but wen I went to check my underwear it just look like my normal discharge so I went to lay down and my vagina was killin me it felt like what a infection feels like I had to keep my legs closed or else it would feel like I was burning (I couldn't move without this burning feeling )but I fell asleep and wen I woke up the burning was gone and my baby is still beating the shit outta me so I know he's fine but now I want to know wtf was going on
