Well it would have been helpful if you had mentioned several other facts like the MCH, MCHC and the MCV which would have been reported. There are diseases where the iron is not incorporated into the hemoglobin and hence the iron levels maybe normal or high but the Hb may be low still. Thalassemia is one such disease but it manifests at an early age, like 5-6months of age, and hence don't fret about it.
Skyla is a small, flexible plastic T-shaped system that slowly releases a progestin hormone called levonorgestrel that is often used in birth control pills. Because Skyla releases levonorgestrel into your uterus, only small amounts of the hormone enter your blood.
Miscarriage, infections, and premature birth may occur if Skyla is used during pregnancy. As this eMedTV page explains, it's dangerous for pregnant women to use this intrauterine device. This page explains why and covers what to discuss with your doctor.
