I feel crazy. With my first 2 kids I was on the pill for one and the nuva ring for the second. This time I have a copper iud and I have had it for 4 years now. Recently got out of a 3 year relationship about 8 months ago and never had even a scare. Been with my new boyfriend almost 5 months and suspect I'm pregnant. I started getting intense headaches, nausea, metallic taste in my mouth and fatigue around the 4th of February. This progressed over time to actually vomiting but still not everything in my stomache so I went to see a doctor. He gave me a test for pregnacy and said I wasn't and sent me on my way. I now have darkened armpits and upper thighs, full out vomiting, line forming on my stomache, hairs on arms and stomache are turning black, back pain, sensitive to smell, hate coffee when I used to drink 3 cups a day, cravings, crazy dreams and extreme thirst. I haven't had these symptoms since my last 2 pregnacys and I was supposed to get my period this weekend. I have been peeing on sticks but no luck. Anyone here been pregnant on a copper IUD?
