Belly feeling like it’s shrinking...

We just recently moved back to Texas and I’ve quit working till baby gets here since I’m already 34 weeks so I have had more time to focus on staying active and eating healthier but I swear I feel like I had a big growth spurt in my belly when we first moved but now this week I feel like my belly is much smaller again...I have a drs appt tomorrow and I’ll mention it to her but it just makes me feel so uneasy. I have already been nervous the whole pregnancy since she moves so much less then my first baby. So I’m constantly wondering if she is ok in there or if she is just positioned different that my first one.

Basically I’m just wondering if any one else is experiencing the same thing. Or am I overthinking everything cuz I’m getting close to the end and the nerves are kicking in. Lol
