I got the mirena iud a at my 6 week pp, I've never had an iud before I've had the nexplanon and the ashlyna pill. With both my other birth controls I never had side effects from them. But these last 2weeks I've been waking up nauseous and randomlyin the day, getting very bad headaches, very gassy, my lower abdominal and back hurt, and then we went on a road trip and about and hour driving I got super bad car sick(I've never gotten car sick) to the point were if I looked up I would get dizzy and throw up. Has anyone had side effects from the iud. WOMAN IN NEED!!!
