Higher amnionic fluid in baby b

I had my weekly AFI check today and baby a was measuring normal and consistent but baby b was measuring 9.1. The max they wanted was 8. The doctor came in and said she doesn't think it's ttts because b's numbers are normal and they're growth is very similar. She's recommending I take another gd test and I have to go back Monday for another AFI. I'm 31 weeks today so it's likely I'll pick up NSTs Monday/Thurs starting next week. I don't see my on until Friday. She said it could definitely be a fluke too. I'm just nervous and worried I'll end up having them early. Plus, baby b's heartbeat was 122. The tech said not to worry about that at all since it was in the normal range and he was resting. last week he was resting too and it was 130. The week before he was moving around and it 140s. I know I shouldn't worry but I'm just a little nervous about this. Anyone been through this. I'm wondering if this is the start of ttts.

 

They are watching you carefully it seems. I know their HR can change later on in pregnancy to a slower beat. Hopefully it is just a fluke and everything is fine.

 

This is bad but I'm thinking that I'll drink a coke before my next appointment to get them dancing so I can see if his rate is higher. Of course they're not concerned with his heart rate only me.
