Gaining and Losing weight

Mia
Anyone else had really weird weight fluctuations during this pregnancy
I wasn't sick, didn't vomit up my guts or get dehydrated or anything, but since March when I conceived to now, I have only gained (retained) 5lbs. 
Here's the math;
I lost 24lbs, gained 7, and lost 2lbs from that 7.
My daughter was already essentially 5lbs when we were 33weeks, and I'm 38+2 now. I never had such weird weight fluctuations with my others.
