Wet Underwear no discharge 🤷‍♀️

Last night I went to bed around 11pm. At my 4am potty break I had to change my underwear because it was so wet; no discharge, didn’t smell like urine. I’m not sure what’s going on. I’m 35 weeks today. I am having painful BH but they go away when I sit or lay down so I know it’s not real labor. Just don’t know what’s going on. I’ve never had this happen with my previous pregnancy.

Updated...Well my water is leaking and now I’m going to be admitted and having a baby soon!
