Underwear and Nursing Bras

Jennifer
I'm a FTM, I'm 15+5 weeks. I just drove 1 hour and 45 minutes to the nearest Motherhood Maternity Store and their sizes were S-XL. The plus size store they directed me too, was over another hour, away from my hometown still. So 3 hours away from home. I was lucky to be given 1 pair of 3x maternity jeans. I found 1 pair of 3x Maternity yoga pants for 14.99 and a pair of 3x khaki's for 19.99 at Sears. I can thrift store shop for 3x-4x regular tops, but now I can't find a belly band, underwear, or Maternity Bra's. Where did you find yours. I don't feel comfortable buying on-line, as you want a good fit. I'm a 2x normally 5'7, 250 pounds, but my clothes are quickly becoming too small. I'm already wearing size 10 underwear, which's the largest size in most stores. Where did you shop?
