So I Have The Mirena IUD And About A Week Ago I Had Sex With My SO And He Came Inside Me. For A Few Weeks I've Had The Feeling My IUD Has Moved Places And I Haven't Had Time To Go In And Check It ..These Past Few Days I've Been Feeling Nauseous And Wanting To Throw Up But I Don't. I Haven't Had My Period For About 2 Months After I Got The IUD. Is There A Possibility I Could Be Pregnant?
