Feeling out of sorts. (TMI WARNING.!)

You have been warned. So I have been feeling out of sorts in a way. Like nauseous a bit, especially after I eat, I am always so tired now, I pee a lot more, yesterday and today my boobs and nipples hurt so bad, my nipples feel like they could be swollen but they aren’t, and my boobs feel firmer. I am getting hot really easily like having hot flashes and it makes me dizzy, my stomach is feeling kind of weird as if I have pressure at the lower part of my stomach along with some light cramping on my left side. On the 18th I had light reddish pink spotting, the next two days I had clear stretchy cm, and then the day after I had a little more spotting my cm is going from watery clear to stretchy again. The first picture is from a couple of days ago.

This one is from today.

Does anyone have any idea what couple be going on.? My periods are irregular and my last cycle was March 18-25. I’m not sure if and when I ovulated. Again sorry for the tmi pictures.
