I am not sure if I am 12dpo or 14dpo because my cycle is irregular 2-4days off every month but this app says I am 14dpo. According to the app, I was supposed to get my AF yesterday but I only had brown discharge. On my usual AF, I don’t get brown discharge before AF. Could this be implantation bleeding ? I tested this morning FMU and it was negative and my brown discharge started this afternoon. I had some cramping for the last 5days and I don’t have it much anymore. I ordered some pregnancy test on amazon and it’s coming Saturday. What’s your thoughts?
