Don't want another negative

We have been trying for over a year to get pregnant. We know its gonna be a hard time, because if my previous surgeries. I cant stand the thought of having another negative test. But I haven't had my period since January. I have been sick everyday (not sure if this could be related to another help issues). I've been so lighted for the last two weeks. I almost passed out at work two days ago and last night. I'm always tired. I just got new bras about an they don't fit anymore. But I just can't get myself to take another test an see it be negative again. Please if you have any advice
