question about possible pregnancy...

hello, I am new to this group. I am 21 years old and My husband and I have been trying to consive for a year. Two months ago, I was diagnosed with a bad case of PCOS.. my doctor put me on a hormone. I am on day 34 of my cycle and have taken two pregnancy tests. they both came back negative. I am cerious if I can even become pregnant? I do not want to become hopeful and be disappointed like all the other times.
