We're building just a little under 2200 sq feet living area. Some upgrades (granite, 10 ft ceilings, crown molding, large garage and back porch), and we're about $77/sq foot living area (about $51/sq foot total under roof) excluding cost of land & landscaping.
How long is the IUD effective? Mirena is effective for five years, ParaGard (copper IUD) effective for ten years, and Skyla is effective for three years. What is an IUD? An IUD - IntraUterine Device is a birth control device (form of contraception) that a health care provider places in your uterus.
It's possible to miss a period while on Paragard for any of the same reasons that you might miss one when you are using no birth control method. Women using Mirena tend to have light periods, but women using Paragard generally have periods the same as before or a little bit heavier. I can just about guarantee that you won't be switching over to a light period.
