old navy maternity yoga pants

Did I spend too much on maternity clothes?
This weekend I bought the following at Old Navy online:
13 shirts, 2 knitted yoga-like capris and 2 knitted yoga-like pants.
I paid $189 including taxes and shipping, so that is about $11 per piece of clothing.
I still need to buy 2 pair of jeans, 1 pair of shorts, underwear, bras and a sweater. That would probably cost me about $125. My mother-in-law said she would buy me all of that.
Do you think $189 was too much to spend on maternity clothes? I don’t plan to buy anymore on my own and we are hoping to have at least 1 more child. (This is my first pregnancy)
What do you think?
I am working mom, so I can’t wear sweats all day, but I wish I could!
Only buy what you need as you need it and a lot of the time you can use regular clothes instead of maternity especially undergarments. Maternity underware is not comfortable.
