What does this mean???

I’ve been having quite a lot of this cm for a few days now. I’ve had a yeast infection and BV before and I’m not having any usually symptoms, I’m not itchy, smelly and nothing’s burning, so I’ve just been going about my normal days. I bled for 3 days about 2 weeks ago and it was light but resembled a normal period so I didn’t think much of it. But now I’m 1 day past ovulation for this cycle according to my app and I’ve been feeling very nauseous constantly, extremely tired and I even cried watching frozen 😂 I’ve taken 3 tests all of which have come up negative but I may have been testing too early. Any help would be sooo appreciated!
