After miscarriage and need help. Glow can you help me out!.... Please

I had an miscarriage back in September 15, 2013 and I have been trying to get pregnant. I had my first period after my first miscarriage and that period was on October 26, 2013. Every since then I haven't had a period since then. I keep on testing and all my pregnancy tests came back negative. Then I went to the doctor's Monday January 20, 2014 and my doctor said I wasn't pregnant. She used an home pregnancy test. I want to have a baby number 2 and it seem like I can't and I feel like give up hope. My boyfriend want me to have a baby by him. We been having sex everyday and night. He don't even use protection when we have sex either. So what should I do now . Someone help me please
