Any suggestions on how I can overcome my plataeu and lose these last 10lbs?

I'm 5'1 and lost about 100lbs between May 2018-May 2019 and have been maintaining since then so right now I'm around 135 but my weight fluctuates a lot especially at different parts of my cycle.

I've been doing Crossfit (which includes some lifting) consistently since 2017 (4-5x a week, mostly 5) and I jump rope every day for at least 16 mintues for additional cardio at home since I hate walking/jogging/running. I try to eat around 1400 calories or under and get at least 115 g of Protein a day. At one point I had gained a few pounds some months ago but I lost it and now I'm still stuck at around 135.

I want to get to get leaner and my goal is to get to 125lbsand maintain that but I'm at a loss for what to do. I've been under 130lbs, very briefly, before but I can't seem to get there again. Any advice?
