I had the Mirena IUD and it had a very low dose of hormone in it, and since it was a 'local' kind of hormone, it didn't work like the pill...so I didn't notice any of the side effects like taking the pill. It just made my periods light to nothing. Which was nice! And this is definitely way TMI, but I kept getting BV infections. So my body just didn't like having that foreign thing in it. That was the only bad thing. No weight gain, no moodiness, no loss of sex drive, no babies!
Now I am taking the POP, or mini pill. I get moody, and it kills my sex drive, and I am still worried about getting pregnant, so I don't really know why I am taking it. I'm still pushing for the vasectomy!!! It is really the only option I see at this point. Or abstinence, which isn't really an option in my book.
