Should I cut my hair?🤔

About two maybe three years ago my hair would never grow past my shoulders and now it finally had thanks to 2 pregnancies back to back but now that it’s finally grown I miss my old hair because it had more volume and it just suited my face better I think and it held a style better, but I have gained maybe 30-40 lbs from being pregnant then getting pregnant again 2 months later (currently 33 weeks) so I have a little more of a double chin and my cheeks are more filled out you can’t tell in pics because of how they were taken.. I also feel as if my hair looks thinner now that it’s longer

^this is the length now

^this was the length before

So what do you think cut it or leave it be?
