30 yr old female, no lost or terminated pregnancies, 2 children. Got mirena in either late 2013/early 2014. I don t normally have a period, except a couple days of very light spotting here and there (nothing too consistent). I started spotting a few days ago and am still. But yesterday I noticed a large, what seemed to be a clot, after I went pee. My urine is normal, though I was a bit dehydrated. My suspicion was either kidney stone (I have a couple small dormant stones in my right kidney) or bladder infection. But I thought both of those things changed the urine color. I have wiped and peed out more of this and it s dark red and sort of gooey. I ve been spotting about 3 days and had the large clump (i did take a picture because it s something I ve never seen before) come out yesterday.
