loosing weight at 8 months?

Summer • 👼👧🤰

My last two check ups I've lost a total of 4 lbs. the last check up was just under 2 lbs and I tried not to worry about it. this time I'm down over another 2 lbs. I'm currently 35w5d. I'm literally sitting in the room waiting for the dr but I was just curious if anyone else had a similar issue.
