weight loss on IVF stims afer 8 years on Mirena

TW: weight loss/discussions of weight, eating

so I was on the Mirena IUD from Aug 2017 to Aug 2025. In that time I slowly gained 10-15 stubborn pounds i could not seem to lose for love or money, even after getting the IUD out last year.

Fastforward to day 8 of stims today and without changing my diet significantly or even working out, i've somehow managed to drop almost three pounds. i'm a little stymied, given everything i've read has said to be careful about putting weight on during stims.

now i'm wondering anecdotally if anyone else has experienced this after being on an IUD long term, and if all this high estrogen is almost like a 'factory reset' for my system, and i just haven't realised how suppressed my hormones were/maybe still are after the IUD which was causing the stubborn weight to stick around.

of course there are no long-term studies looking at this, (but when has women's healthcare ever been a priority to study.) plus i feel like this is a difficult thing to replicate in a study/lab as there are so many confounding factors so i doubt there will ever be good evidence supporting/against it.
