Fertility issues ?'s: You may be very fertile or did not take your bcp's punctually. After your second child, a Mirena may have shifted position from uterine contractions. Even a "tubal ligation" can become undone, and pregnancy will occur. Obtain a serum HCG to make certain about current pregnancy. See your gyn physician if test is positive, because a pregnancy outside the uterus may be possible (ectopic).
