Hi Ive been on Evorel conti patches for 6 weeks and have experienced all types of side effects, headaches, period pains (have had no bleeding) excessive wind, bloating, frequent weeing, anxiety, nausea, constipation, heart burn, tearfullness, irritability - you name it! each side effect has only lasted a day or two and then another one comes along. Ive been advised from both the lovely ladies on this forum and my GP to stick it out for another 4-6 weeks to see if everything settles. I guess your body needs time to adjust to any new chemicals that enter your body. Good luck and let us know how you get on. x
