I was started on Loestrin 20 at the end of June for pelvic pain (which i believe is endo). I was told to take the 3 packs back to back. I am half way through my 2nd pack and have been spotting for a week. Is this normal or should I go see my doctor. I have also been getting headaches, feeling very nauseous and been having hot flushes and not been able to get a coldness in my body.
