Super confused, can anyone help.?

Hi ladies. I am wanting to see if anyone has been through I am going through, or could possibly know what is going on. So last month I got af naturally. I spotted kind of like a light to medium spotting, I needed to have something on at all times, so I spotted like this for 10 days and had af follow for 8 days after, this month since the 2nd I have had very light spotting but with small clots and a lot of stretchy cm, sorry TMI, the last couple of days I had some dark reddish brown spotting and it has kind of gotten heavier, but it never keeps going to a full flow. The only thing is, my boobs have been really sensitive, I have been really tired, my emotions are more out there ( I never really cry for anything, and I start to almost cry for anything right now ) and I have had some nausea. I took a PT and it was negative, I haven’t taken one since.
