i had the mirena out 2nd March, trying to get pregnant, i had it put in for heavy and irregular periods, since it came out i have had a period that lasted for 3 days and then nothing, which is very unlike me, normally if iam not on any form of birth control then i just bleed all the time. since the mirena came out i have not taken any birth control and had unprotected sex several time, but there is no period, could i be pregnant? is amy one else going through some thing similiar. thanks for any answers..
