I have had the Kyleena IUD for about 2 years now. The first year I had it, I had no period, only occasional spotting. Then after that year invariably got a period and had one every month. In January I started having stomach problems that made me constantly feel waves of nausea. My doctor got me on an acid reflux med and it helped a lot! But I also haven’t had a period since January. My boobs aren’t sore or different, I haven’t had any weird food cravings or anything. The only pregnancy symptom I have is the nausea and the missed period! Should I be worried?? I do have sex regularly with my boyfriend but he does pull out.
