is this normal also ttc

My periods have been pretty regular, been ttc for a little over a year and i feel like since then i’ve became more in tune with my body and actually know what’s going on. i literally sit here and nit pik every symptom and mentally i’m drained. last couple months i know i was spotting light pink/brown one week before AF then when expected it got heavier for a day after my workout then light spotting for another week so i’m confused i’m considering it as AF. LAST month i spotting 3 days before AF and it happens here and there i also have ovulation bleeding too and bad cramps some months no symptoms.

AF is due tomorrow ( comes early most months ) and no signs keep checking and nothing been having light cramps here and there but rare and been feeling nauseous today at the gym and for bed.

what do you guys think is going on with my body ?
