21 weeks and possibly leaking fluid


So i called the on call and they are checking me tomorrow. This has been going on since Sunday now. I'm hoping with all my heart its not a leak. I finally got my boy and im terrified im going to lose him. I lost his twin at 6 weeks and found out I have a posterior fundul (?) placenta but they never actually called me to go over it and what I've found is its associated with preterm labor so now im terrified 😭😭
