Lost😔

I'm 18 and having some issues. I don't know what to do at this point, my husband and I have been trying for a little one, but nothing is happening. My period is now two weeks late. I took two tests the day after my missed period and nothing. Well my husbands two really good friends just announced that they are pregnant, and the month before it was his other friends that were announcing the same thing. And each time he gets so excited for them. He wants a baby badly and so do I, and I'm at the point where I've just been saying that I don't want kids because I feel as though I am disappointing him because I haven't gotten pregnant yet. I don't know what to do, and I have no idea where my period went.  😕
