This is a good question and a questionable one coming froma mum or mom of four under 10 years old. I dont know all I know is that I have been using Ortho Evra for a good 6 years ( of course taking a break to have #4 and during pregnancy) has it been effective DARN right I only have four. I love my kids I enjoy them they have brought the best out in me whilst workign the worst out in me to get to the best. LOL And I admire any woman whom has a heart & desire for more. However this past year 2009 during Michaels last deployment I decided to give my body a break at the same time I began using Young Livings essentail oils & products. I went down 2 belt sizes , had more energy, I was waking up better, I drank less coffee and didnt need one during the day. I did not think anything of it. Well hubby was coming home I DID NOT WANT TO BE HAVING #5 so I started getting my body used to the Orthro Evra but this time was not good. Crippling chest pains to the point I was bent over and havi
