TTC. I need a little hope for BFP.?

Hubby and I are TTC after our first ended in a miscarriage a few months ago...now im super sensitive to the topic and worry about every little thing...I was hoping you all can read the scoop and let me know if I still have hope...We checked my "O" day and tried every other day leading up to "o" day and then a few after to make sure :) Im at 11 dpo, and i have had nausea, headaches, light cramps and a runny/stuffy nose at very odd times of the day, i would wake up in the middle of the night with one. I have also had dreams of BFP and woke up thinking for sure this is the month, but with the cramps im not so sure. I have also had sore BBs but someone suggested i could be wanting it so much that I have made myself feel the syptoms...Any one have any advice? I did a HPT at 8 dpo, but it was BFN. Im sure it was too early but i have little patience and hope left.. Would like to know if anyone else is or has been in the same boat and got their BFP all the same. Thanks to all!
