Hair advice!

Roni
With my first pregnancy, I loved my hair! It seemed to be thick and healthy and beautiful. However, this pregnancy (in many ways) is very different! My hair seems so damaged and dry and frizzy and I am losing a ton of hair! 
I have long mostly blonde highlighted hair- and at this point I just want healthy hair. I am thinking of cutting it mid-length and doing an overall hair color instead of highlights. However, I am also tempted to just leave it be until after my baby is born.
What would be the healthiest choice for my hair? And is there any certain suggestions for hair color/cut that are healthier than others?!
Here is a current pic of my craziness!
