Too much fluid??

Lindsay • 30 years old,2 daughters 11 and 10 to a previous! 1 AngelBaby baby #3 after ttc 4 years! Love my Liam lots xxxx
I've been scanned today because stomach was measuring 35 weeks at 31 and a half yesterday. I've got too much fluid and baby is measuring perfect. Now I'm paranoid that there's something wrong with him. Anybody had any experience with this x
