Currently 20 weeks and right now feels great and supportive and stays put. Although I am unsure whether or not it will carry me to the end of my pregnancy to be honest. I purchased my pre-pregnancy size (S) but this is my 3rd pregnancy and while my weight gain has been the same between all, my stomach is much larger than I was at 20 weeks with my first pregnancy. I cannot see how I can get another 20 weeks out of the band, maybe 8-10 weeks at best. I also noticed the size chart printed on the product packaging is different than what is online.
