I got my mirena removed last thursday and had what I believe was a period that Saturday that lasted 3 days. my periods are normally longer but I was cramping etc so I'm sure it was. Anyway so now 6 days after my period ends I'm having brown discharge, cramping mainly on my left side and I'm crankiner than normal. is this due to getting it removed or any advice?
