Using less insulin while pregnant?

Hi everyone,

I’m 16 weeks pregnant with my second daughter and I have been having a lot of lows. I’ve had to go down on my pre-pregnancy basal rates and go from a 1:10 to a 1:15 CHO ratio. I am still getting lows and need to adjust my basal rates again. I am actually less active and have less muscle mass than I did in my first pregnancy. I thought it was very odd that I’m using a lot less vs. having to increase my rates due to developing resistance. Has anyone experienced this, too?
