Another missed month ... Frustrated

I feel like we're doing everything right. opk's read positive and we dtd. Everyone in my family had kids so easy! I went to the doctor as this is our 10th month trying and she said "keep trying and come back in 3 more months" it's so depressing. I'm losing hope. We had a chemical pregnancy back in January and I was sure I could conceive again after that. Anyone have any luck trying anything new? Any advice would help. AF due the 8th tested both blood and test both BFN :(
