Excessive fluid around my baby

[Mimismummy]

Hello im new to here and hoping someone can help. Im 25 wks pregnant and found out last week that i have excessive fluidaround my baby. Tjis was a shock and was greeted with me being told i need to have numerous tests for diabetes, Torch,Parvo virus which can all be the cause but all sound extremely worrying. My baby still as active as ever using my uterus as a football hahaha. I cant stop from worrying abd yhinking the worse has anyone experienced this??? My fkuid is currently at 11.4. Thankyou in advance xx
