Light pink and brown tinged CM.

I’m either one or two days late for af depending on what day I actually ovulated.(it was either the 1st or 2nd of August) Been super nauseous like motion sickness in the evenings this last week, sore breasts and cramping. Today when I wiped I found very lightly tinged pinkish brown discharge on the toilet paper. It was very stretchy and almost like Ewcm but tinged. I tested today with fmu using frer and it was negative though 😔 im sure it might be af coming but wanted to see what you all thought. I was having cramping earlier as well with the discharge but that seems to have stopped and the discharge has lessened a lot from earlier in the day. If AF isn’t here tomorrow I will test again.
