Is anyone else getting sh*t for buying maternity clothes?

I'm 20 weeks with a big healthy bump and getting a fair amount of flack for buying some maternity clothes?

I'm being told it's a waste of money and being compared to other people who didn't end up buying any "just some stuff in the size up"

I've not bought a lot just 2 pairs of leggings, a few t shirts, pair of work trousers and a shirt for work and all for very cheap (even used my 20% loyalty discount too).

Just wanted to see if anyone else was getting the same reaction or just me?
