i have an iud, but i think i might be pregnant, i dont have medical insurance to find out, but i dont know what to do, i have had my iud since November 2008. when i lay down i feel a hard area, like a pregnancy would feel except behind my " baby fat" and when i layed down on my bed earlier the hard spot shifted almost like a baby would so i pushed on it and it moved back. HELP am i going crazy or am i pregnant? My lower back really hurts and has for a couple days and i was having cramps yesterday. I dont get a period at all. I have wondered for several months but i dont have a baby bump, and im not a heavy person beside my little baby pouch?
