So confused!

C
I'm so confused! So long story short I believe I ovulated later then I would usually. Af was due technically yesterday... but because I feel like I ovulated later id be 10 dpo at the latest. Ive tested and bfn. Yesterday and today ive had on and off very light brown and pink when I wipe and then very watery cm (which yes could be af but also implantation bleeding). Morning time it seems im having pms symptoms. But that's really it, oh and cramping on and off but noting crazy. Should I keep testing or is anyone in the same boat? Feel like I'm going crazy here. If af doesn't show by Monday morning im calling my doctor..
