L.B.
I have used Mirena it is an IUT. I liked it because it had a very low dose of horomones, which was nice since I could not take pills without turning into a horomone on wheels. I never had a problem. I had it inserted 6 weeks after the birth of my son and had it taken out a few months ago. It does not hurt and you do not even know it is there. A bonus was I did not have a period for the entire time. You can go on their website. Mirena.com It has alot of info. It lasts for 5 years. It is as effective as sterilization and it can be taken out at any time. It says you return to normal fertility almost at once. I had my period about 4 days after having it removed. I would definitely recommend it! Hope this helps
