Hey Kylie,

My body's done something similar after being off contraception for just over 12 months. I was on depo though.
I went from 28 days cycles down to 21 (what they were pre baby) now back up to 26-28.

I did find that when my LP got really short a herb called vitex helped. I was prescribed by a naturopath though.

You have done a fantastic job with the weightloss and your hormone levels may still be adjusting.....
