Please be very cautious and wise! I have an IUD and it sounds like it may not have been put in the right way. I love it because, afterawhile, you can hardly feel it inside your body. However, proper insertion is extremely important. The first doctor inserted it wrong, the second doctor inserted it perfectly withing 5 minutes. I would get a second doctor's opinion, if possible. Also, if you and your spouse are considering another child, make sure you see if you need treatments. Because some nutrient levels are low after the first and second baby.
Best Wishes,
D.
