So y’all I been on the mirena for a year now and lost month I didn’t have a cycle it was just like spot then this month I didn’t have it a lot but I have like the symptoms of a period like mood swing , cramping , boobs are sore headache. Is is that because my cycle has stopped completely and my body is thinking I’m having one like what I’m basically trying to say is that more for this kind of birth control for the people that have this kind of birth control and had it longer than me I know everybody’s body is different just want to be sure.
