When to test?

Ke

I’m currently 12dpo and I tested on 10 and 11dpo and got bfn both times. Last night, i had slightly pinkish-beige cm and was having some light cramping. Nothing this morning. Does that sound like implantation bleeding? Af isn’t due until 5/7 and I never usually have spotting. Should I just wait to test again until after af is due? Last pregnancy, I didn’t test at all until I was 3 days late. I’m just so impatient!
