Hello, I am around 14DPO and noticing some weird spotting. My cycles are irregular and my period is supposedly due within the next 2 or 3 days.

I was having CM with some dark brown in it 3 days ago, yesterday evening I had a lot of light pink discharge and some CM with blood in it. Today, I had a very small blood clot with dark pink spotting. It is now turning bright red and is only showing up when I use the restroom and wipe.

Could this be implantation or does it sound like AF is coming? I had usual PMS symptoms (tender breasts, increased appetite, mood swings) and nothing out of the ordinary, but most of them have gone away now. Any ideas on what to look out for?
