Bleeding/periods after mirena insertion

I know your period is supposed to be a little wacky for a while after mirena insertion, but I feel like mine is getting a little out of control. I got it put in march 9 (144 days ago) and I've bled for a total of 74 days since then 😰. Not as heavily as a normal period but heavier than spotting. I keep hoping it will even out as I get close to the 6 month mark but it's still all over the place! What was your experience? At what point should I just give up?
