I just started Loestrin 24 last mth n have been having excruciating back, stomach & side pains which caused me to go to the doctor. I haven't had a period, but I don't blame the pill, I was on the Implanon which caused me to have cysts on both ovaries and side pains. While on the Implanon I didn't have any periods, and now on the pill I still don't have a period. I have noticed that once it get to the end of the pill pack and I am suppose to have a period that's when all the pain starts. I am looking into other options.
