Hi, I am currently taking Lutera (birth control) and noticed a very light 3-4day period during my placebo week. Almost 2 weeks later, I noticed brown discharge for a day or so and then bright red, heavy flow for the next 5days. I m on day 7 and I m still having a relatively heavy flow (having to change out a heavy/max tampon every 3-4 hours). Some other symptoms I ve noticed are severe back pain to where I can t walk and stand up straight. I feel nauseous and have a loss of appetite that I thought was due to stress.
