I was PG around the same time as you and I bought 1 pair of maternity jeans when I was 16 weeks and 4 maternity t-shirts but that is all. I also had a belly belt & didn't wear it until 25 weeks. So I guess it all depends on when you "pop" and comfort. We didn't have much $$ so I went op shopping & bought a few pants which were too big & singlets and that lasted me. I was so warm that until I gave birth in June I didn't get cold.
