Hormonal coil (IUS) and tender breasts

Year 1 was a lot of hormonal changes, strong random cramps and spotting (i had to get the position adjusted slightly about 8 months in), but the effect on my periods was almost immediate. Regular lighter periods with reduced cramps(outside of above) that no longer impacted my life negatively. It's a game changer. Once that all settled down, I was abel to start tracking my periods and moods and for the first time in my life knew when something was "outside the norm" and could get things checked out as they came. The positive impact outweighs the negative by far in my opinion. Peace of mind and regular light periods is absolutely worth it for someone who's emotions and hormones and periods have always affected negatively (before jaydess I'd pms what felt like 3 out of 4 weeks, cramp so hard id pass out and bled through so many clothes)

First 6 months is an adjustment period so I had plenty of headache and feeling sick but after a while my body used to it and I am fine. 100% contraception effectiveness and no heavy period.

Generally the Mirena has been great. Only noticed most of the side effects after 4 years having it in - and they’re still very manageable.
