I get my IUD in Thursday morning. I’m very nervous. The pill caused me to have horrible migraines and i was sent to a neurologist, so this is my best option. My gyno is giving me a pill to insert inside me to help me dilate. My period symptoms are horrible as is, heavy flow, horrible cramping, etc. Will it make things worse? Also i have a bad feeling i’ll bleed for a few months, has anyone taken a pill to help with that? I’ve only heard about one person doing such. Any advice?
