Here is my story, PLEASE let me know if I have a chance still! I'm confused!

Jenna
My last AF was Sept. 22nd & followed by stopping my birth control pills (in which I have done before with my 2nd son) on Sept. 27th (approx.) I BD'ed on Oct. 5th, got a positive ovulation test on Oct. 7th so then BD'ed again that night. We didnt BD again til later on in the month. We are trying to have a little girl so we are trying to time everything perfect around ovulation. After all that my AF was suppose to be due around Oct. 22nd or so from what it all calculated out to be... AF never showed & its not the 27th! I have an obsession with taking HPT's & each one has said negative.. to this day. What might be going on? DId I ovulate late, if so did I lose my chance of getting pregnant this month? I wish AF would come if shes coming so I can plan for this upcoming month....?! I'm trying not to stess over it, but its more irrating then ever! My body has been throwing me off n on again symptoms of Af possibly coming or pregnancy symptoms- who knows?! I need some friends to help ease my mind... PlEaSe!
