TTC complications...

So i am 18, my SO and I have been trying to conceive for 6 months now. Its been a rollercoaster unfortunately.... At the beginning my periods were a week late then normal and now they have been coming a wrk early. I really thought this month would be it because I was spotting around ovulation week and then a few days ago, but yesterday I'm pretty sure I got my period..I made a doctors appt for Monday so I'm hoping to figure some answers out.. I just wish that I could come home or take a test and say your going to be a daddy! ..... Has anyone else talked to a doctor about fertility issues or wanting to get pregnant? He's a guy so I'm kind of worried!? Hmmph
