Ive been trying with my husband for over a year.. . And nothing. I was just looking for a probability of this time going through. PLEASE, I NEED ADVICE.

There is no way we can give you a percentage of possibility of pregnancy. You will have to wait to see if your next period comes as expected. If not, wait until it is two weeks late to test using first morning urine.
