Feeling anxious

Help! I’m currently at 38 weeks 2 days and it’s been 2 nights i keep on having tummy aches wanting to poop but very little come out and before i poop, my vagina will leak like watery discharge and my panties will get wet. I don’t know if that’s my water bag or just pee cause it’s transparent and watery. I’m a first time mum, I don’t know what to do. Anyone feeling the same or have experienced this? I’m tested positive for GBS so i’m worried about my baby. #FTM
