What I do like about preggers is that the compression stockings are what my doctor recommended from 10-15mm hg. The thing I do not like is how the feel on my leg. My thighs get very sweaty and I feel like I cannot breathe in them. I like the way spanx feels more than preggers stockings feel; they are much more comfortable and I can wear them all day. I can only wear preggers stockings for pregnancy for about 1-2 hours. Spanx does not have 10-15mm hg stocking available on their website so I wear a mixture of preggers stockings and spanx. I hope I can prevent varicose veins by wearing these stockings. Will let you know if they work.
