is it just me or the longer you've been trying the less often you symptom spot?

Tracey • Ttc since September 2013, hoping for another miracle baby!
I've been trying this time since September, last time was 2 years. I've had every possible symptom from sore breast/nipples to bleeding gums that start around 10dpo, then suddenly stops! After getting all of these for so long and getting the witch every time, I've found it to be easier now to not symptom spot.
