I'm very nervous I might be pregnant, I keep feeling flutters when I relax at night and bloated I have the mirena coil in 6 months

It is not common, but it is possible. No birth control will be 100% effective. Fluttering type feelings can be from a variety of causes. You can always try a pregnancy test. If you were far enough along to feel fetal movement, you would get an accurate result.

Thanks for your help I appreciated it..
