Excluding my skinniest jeans, I wore mostly regular clothes until maybe 22 weeks. On high-bloat days (I was on a lot of support meds for my first trimester) I wore stretchy pants or unbuttoned pants with a belly band over them. I did wear some maternity shorts/jeans along the way, but they were definitely interspersed with regular pants. I'm now 32 weeks and still wear a lot of regular dresses and loose tops.

This is my 1st pregnancy and I really just went from the "perhaps she's had too much beer lately" to the "definitely pregnant" stage in the last couple weeks. I'm up about 23 lbs.

OMG - within the first 12 weeks. How depressing. I have mostly a food-belly right now, but I just couldn't get into my regular pants anymore. This is my 4th though...

20 weeks i didnt think i needed it because i just wore my big old pants, but when i finally bought some it was just so comfortable and my shirts were long enough not to rise

I'm 39 weeks and I really didn't buy maternity clothes this time around (3rd pregnancy). I have one pair of maternity capris that are still kind of big on me, 2 dresses, and a t-shirt - none of which were worn until the third trimester. I still wear my regular clothes, though last month I had to start using a waistband expander to button my pants.

Around 18 weeks I started switching over to maternity clothes. This is my second pregnancy so I already own a bunch of clothes and decided I might as well get the most use out of them since you wear them for such a short period in the long run.

With my first pregnancy I was doing the hair band button trick from 12 weeks until maybe 20 weeks when I finally switched to maternity clothes due to the season changing and I had to buy new clothes anyway. I'm thinner this time so those pants still fit buttoned up at 21 weeks but are getting tight.

With my 1st baby it was probably around 17 - 20 weeks before I started wearing maternity clothes.... however back then I wore baggier clothes... Plus with the 1st I didn't find out about that pregnancy until I was already 17 weeks and some days.... With this baby I found out I was preggo at 5 weeks... my clothes are definitely more fitted as I was proud of my shape .... I bought some of those belly bands to wear with my regular clothes/pants probably around 8 weeks... I bought maternity clothes probably around 9 - 10 weeks and started wearing the pants pretty soon after as they were just more comfortable.. although even now at 15 weeks I still have to pull the pants up some.. it's all about being comfortable for me... I just recently started wearing maternity shirts a few times a week.. only because most of my regular work shirts are shortish compared to the maternity pants so I wear them to cover the belly coverage.. last week I still work a pair of my regular work pants and the belly band.. but I paired it with a maternity shirt to cover the band completely.. so I guess I'm still half and half.. when not working I wear maternity jeans or regular yoga pants and my regular t-shirts (Guy Harvey or Salt Life)..

I'm just over 17 weeks and still in my regular clothes. But there are a few pairs of pants that I no longer wear my belt with.. they stay up rather fine on their own.

11 weeks. I could (and can) still fit into some of my pre-pregnancy stuff but I'm so much more comfortable now.

Wow, I'm impressed by you ladies that could wait so long. Pregnancy #1 I bought maternity pants at 5 weeks from all the bloat but started regularly wearing them about 8 weeks I believe. Pregnancy #2 I wrote that I switched to stretchy pants and maternity pants somewhere in week 6. Pregnancy #3 (current) I'm 8 weeks and worn maternity pants I think twice now, but with the bloat being gone I'm back in regular pants. I'm 22 lbs down from Preg #1 and 12 down from #2 so curious when I'll need them since I'm so much smaller! I have plenty of clothes, BUT I did buy smaller maternity pants because first of all I wore my old ones to death (read holes in thighs from friction) and second because I'm 22 lbs lighter! I'm 5'3" though, so once baby starts growing they have nowhere to go but out, so I get huge. 1st I lost 6 lbs early on but bloated insanely, 2nd I lost 2 lbs, but bloat was bad again. I wonder if I'm not as bloated because I eat better now.

I started probably around week 12-13. I still wear regular clothes w/ the belly band, but that's starting to get annoying since some of my pants are so baggy in certain areas, it doesn't want to stay up. I'm 18 weeks now and going to purchase maybe one or two more pants and some tops as well. Definitely need maternity sweaters!
