I have spent the last few years suffering with what has turned out to be endometriosis and PMS. I have got the endo under control with diet, exercise and CBT for anxiety. I am not on any contraceptives because the combined pill made me ill and I had a mirena coil but had Chronic thrush at the time and dealing with that and the coil was too much so I had it removed. I've spent the last few months documenting my menstrual cycle. I had a laparoscopy 2 years ago. My period is back normal after being extremely heavy and painful (that is due to positive diet changes and vitamins/supplements I believe). My cycle is like clockwork. I have noticed that it's not PMS that I have by post period symptoms. When my period finishes from day 5 to day 14 I am depressed, constipated, bloated, losing my appetite and extremely fatigued. Day 15 to 28 is really good. I am calm, relaxed, happy and well apart from minor symptoms prior to my period. I believe I am reacting the rising estrogen at the time when there is less progesterone. I think I am very sensitive to estrogen in the follicular phase so much so that today is day 11 of my cycle and I can barely function. What can I do? Would the mirena coil help. Do I have an estrogen imbalance?
