Why don't I have periods with my IUD?
I've been on my IUD for about a year & a half (in September 2012). Since I had my IUD I haven't had a period at all, I never even had any signs of having a period. Before I got my IUD I had my periods around the end of each month, usually every 30 days, from the time one would end to the next one to start it would be about every 30 days... sometimes 29 days and sometimes 31 days... but mostly 30 days. How do I know that I am not pregnant, and I am too afraid to get a pregancy test. I want another child, but not yet. Also should I be going for checks up to make sure my IUD is working?
