Mirena Help

Whit

Soooo I have been on the Mirena for like 2 years now and my period has been weird since. Well I’m late like a week I’ve have some spotting/light bleeding, no cramps, bloating. . . I’m sexually active with my fiancé and we don’t use protection 🤦🏽‍♀️ how likely is it that I could be pregnant??? Or could this just be a side affect of my Mirena
