Mirena Advice

Hey ladies! So I got Mirena inserted on Friday 2/22 and it’s been great so far! (Stopped my bleeding and no cramps) I was on my period when I went and got it inserted and my period stopped the next day 2/23. I’ve been an emotional wreck though which is so NOT like me. I’m not snappy or irritable or sensitive but I have been since the day after I got it inserted... Could it possibly be from the Mirena or am I just going through something? Because they said it should not cause mood swings and the hormones aren’t in my blood stream, but contained in my uterus. I have to be on birth control because I have PCOS and my periods will literally last months if I don’t. I’m 6 months postpartum and tried nexplanon but it made me bleed like crazy and I gained 5 pounds after having it in for 4 weeks... Then I went to the traditional pill but if I miss it by even an hour I will start to bleed and it won’t stop till I start a new pill pack. I just don’t know where to turn. Is this in my head or did anyone else experience mood changes with Mirena? I feel depressed and super snappy. Like I clean my grandparents house for them and my grandma asked if I would revacuum the living room because her dog just walked in and got grass on the floor and I literally was almost on the verge of tears I wanted to scream because her dog isn’t supposed to be in the living room because she’s so crazy about keeping it clean and I was mad I had to go redo it.... it’s just extremely unlike me. Any advice would be appreciated.
