Most women actually have the size they need and believe it is too small, if it is 1-2” shy from closing DO NOT exchange it! I know it looks scary but the truth is that it will fit you, remember you need to pull it around tight, it’s a compression band. After you deliver you’ll see it should be very tight but do-able! Even if you have to wait a day or two – we would rather it be too tight than too loose. You may want to try laying down flat with the band under you as you lay on the bed to adhere it that way. Similar to putting a pair of really tight jeans on. If it is 1-2” shy of closing do not exchange it, wait a day or two!
