I have had an irregular cycle ever since I had my IUD removed in January of this year. I started a normal period the day after it was removed and then it was 41 days until my next cycle. The last two cycles have been about 30 days apart and I am TTC. Last month I had pinkish brown spotting about the time I was supposed to be ovulating. This month I started my period on the 2nd and thought I should be fertile this week, but now I've had brown spotting for the last 3 days. Anyone have any ideas about what's going on with my body?
