Monthly wicked migraines, right before period starts. Sometimes lasting on and off for 2 1/2 days. I had one so bad I had to go to the ER. I've never had problems with migraines before in my whole life. A few were very bad and makes me not want to do anything all day. I went to the neurologist just to get a pain medication for this. Also was diagnosed with allergies last summer because I had 2 bad sinus infections. Recently I have started to have acid reflux every night and now sometimes in the mornings. This sucks!! I am getting this removed. I did several internet searches over the past several months and all these symptoms are caused by progestin (levonogestrol). This is not worth it. I've had this thing in for over a year now, but all these symptoms appeared after getting this thing in. Ive also been very moody around the time of the month, super irritable and bitchy. My gyne suggested to take another drug to counteract, (basically prozac with another name) but that's like taking speed to counteract a downer. No thanks!!!!!!!!!! I got this thing put in because of heavy periods, but it is totally NOT WORTH IT!! My health has suffered because of this.
