day 8,9,10,13,14 and 15 of cycle ( ovulated on day 14) fertilization occurring?

Looks like you covered yourself hun!! It is poss to experience symptoms this early but you'll need to wait a bit to test as Im sure you will know, implantation can occur anywhere between 6-12 dpo. Im currently 4dpo so I know how frustrating it is!! There's a great website where you can wait it out with other ladies in the same place as you, Babyandbump.com, its great for support and advice!! Good luck.xx
