Hi, I ve had the mirena iud in for over year now. Occasionally I get left sided pelvic pain a few days before or during my period. Other than that, no issues. Aside from the weight gain. My periods are light and irregular. Blood is always a dark or light brown and consists of spotting for 5-7 days. Never heavy. Today, I noticed a bright red bleeding when wiping, along with the usual brownish blood I get. Should I be concerned? I have slight cramping/pressure in my lower pelvic region, but nothing unbearable. And the blood is minimal.
