I am currently 12 days post <a href="https://glowing.com/glow-fertility-program">IUI</a> and 11 DPO. I just went to the restroom because I’ve been cramping for the last 3 hours and I felt like my period was about to come at anytime. When I wiped, I saw a dark brown substance. I normally get light pink or red spotting the day that i start my cycle. Can someone help? I’m not sure what is happening right now but I am terrified. My period is not due until 6 February and today is 31 January.
