Help lol clothes no longer in

So 14 weeks pretty much in pregnancy clothes. Go invite get rid clothes that im sure won't fit me evan after birth im selling Giving etc , but ones that may I want store keep and see. How long did you wear pregnancy clothes after birth? Also did you treat your self even 2nd hand like charity shops after? Im due oct 23rd my son is 7 christmas eve so if I do that be more new year. I have a lot clothes to.

One idea is sell and keep money for more new year, did gain weight before falling pregnant so I know may nof lose it
