I honestly think I had an allergic reaction. I also had swollen feet while I was on the patches. We tried estrace orally but my body didn't break it down properly and never grew a lining. Del estrogen isn't available her in Canada so we moved to estrace vaginally and I built a 13 triple stripe lining! It's definitely not worth trying the patches again when there are so many other options! I hope tomorrow you hear some good news about the frosties!
