There are a million pregnancy symptoms. A good site that a lot of us have visited is
Early Pregnancy Symptoms and TTC Success Stories at TwoWeekWAIT.com but you can type in early pregnancy symptoms on google and have pages of information available. I know that even the smallest things can drive us insane. I too have learned to hate HPTs and would rather wait for AF and if it doesn't show after 7 days then I'll test. I've gotten to 5-6 days but never 7. So the call is up to you. Do what you think is best and what will help to put you at ease.
