Hi, I got mirena inserted 4 days ago and had a few questions. First, my periods are always regular and this month it was 10 days late, negative home test and 2 negative urine tests at my doctors office but I had a lot of symptoms of pregnancy. My breasts became sore and my nipples started getting darker, I was sleeping more, craving food, getting sick etc. I got my iud put in 4 days ago and as of yesterday started passing grey tissue. Is it possible I was very early in pregnancy and the tests just didn't pick up the pregnancy hormone? Or is it just my imagination playing tricks on me and I'm getting this grey discharge for no apparent reason. I'm currently finishing my a lot lighter then usual period, and something just feels off. Could my body be rejecting this thing?
