Absence of symptoms, possibly a good thing?

I should start AF in the next day or two (30 day cycles for several months now) and for the first time in months I don’t have the normal intensity of cramps (I’m not complaining). I’ve also noticed CM that is abnormal for me at this point in my cycle. I understand everyone is different but mine is almost like clockwork. It’s thin, watery, clear, and abundant. Other than that, mildly sensitive nipples (by this time it usually hurts to even wear a bra). I’m waiting to test until I’m actually late but the optimistic part of me wonders if anyone has NOT noticed their normal PMS and had a positive outcome. Please share!
