First of all, how old are you? Secondly, get educated on the topic. They can give you ovulation inducing tablets such as clomid, artificial insemination even ivf if you are truly committed. If you've been trying for more than twelve months a specialist will speak to you and send you for test to establish the problem so they can fix it. Sometimes it's nothing sometimes it's not nothing. If you're serious about the baby thing see someone now rather than later I waited and it took me seven years to realise I needed ivf thanks to blocked (scarred) tubes.
I would suggest though if you're under twenty-four or twenty-five that you get yourself to college so you can take care of the new bub!
Also I wouldn't have a child with someone who was just a boyfriend. Wait till you're married and settled. It's a beautiful time of your life so you don't mess it up!
