It's easy to get worked up at times like this. When I was 35 weeks with my 2nd boy, I fell over and was convinced my waters had broken early. Turns out I had just leaked in a urinary way I spent the next 6 weeks on crutches (he was born late) but was fine when he was born and he is healthy four year old now.
I'm 26 weeks with my 2nd and have had to wear liners constantly due to leakage for a while now. Doesn't matter how often I empty my bladder I genuinely have to pray every time I sneeze or cough. Pregnancy is so glamorous!
I'm sure it's just that but definitely get it checked out just for peace of mind
