Trying to conceive

So myself and my husband have been trying to conceive since September, we have intercouse every other day and during my fertile window he have sex everyday, sometimes twice a day. I take my folic acid and I believe I'm doing everything right. But every month still nothing and to be honest it's really upsetting me. I don't understand what's going on and when my AF turns up it destroys me. I just want to have a happy heathy baby and make our family complete. I don't even get excited about doing a pregnancy test. I just feel like what is the point. I fully understand that I could be worrying prematurely and some women have been trying for years but I just feel so emotionally drained by this and I just need some advice.
