Breastfeeding after weight loss surgery

First time mum to be here, due in July. I'm planning on breastfeeding but due to the lockdown all classes are cancelled.

I had weight loss surgery just over a year ago, and in total have lost around 14 stones in 3 years which has left me with saggy boobs and excess skin. I was wondering if anyone had any experience of trying to breastfeed with this issue?
