9 DPO and still BFN!!! Please help!?

I have tested about 8 times over the past few days and today I am 9 DPO and still got a BFN. I want to be PG so badly...I had a MC in Feb. and I really want/need to be PG before 9-28-10 b/c that would have been my due date with the 1st baby that I lost....My hubby and I are TTC and we BD during ovulation....One other thing my are so sore and tender the only other time my s were this sore was when I was PG (Before i lost the baby at 7.5 weeks) Do you think I still have a chance of being PG and getting my BFP this month?
