Weight loss after birth

When I got pregnant I was on a GLP1 weight loss medication. I was hoping to lose a bunch of weight this year but got pregnant instead. I’ve struggled with the fact that I would gain weight and it’s been a mixture of emotions.

I’m 36w and so far have gained 46 lbs.

I’m planning on breastfeeding for at least 9 months. After that I’d like to pump but wean her off.

During the time that I’m breastfeeding I’m planning on doing home workouts.

After she’s weaned off I’d like to start a GLP1 medication again if needed.

I’m wondering for those who’ve already had babies, how much weight did you lose in the first year after birth? How?
