Hey Sarah,
I totally empathise!
I also have the mirena and patch and today, feel like death ( literally) Tummy ache, period pain, fatigue, irritability etc etc.
I cannot tolerate anything higher than the 75 patch, but feel so ill right now. What dose patch are you on? I’m wondering if my mirena has dislodged.
Have you just upped your patch? If so, maybe that’s why you are bleeding? Could it be a fibroid? Thin womb lining? Rogue period?
Wish I had an answer for you, but struggling so much myself today. My anxiety was so wretched, i could barely drive 😕
