What should I do with my hair?

Kyanna
Hi everyone. I'm currently 19 weeks pregnant and have been feeling pretty crappy about myself. I would like to do my hair in some sort of style to help myself feel a little better. I've had many different hairstyles and am not afraid to chop a lot off. Thanks in advance!! Oh I'll add some pics of how my hair is now and how I've had it before. 
This is currently lol
This is with shaved sides
This is really short
This is when I was in middle school with long hair.
