Biological Clock Ticking


I am about to be 30 in about a week, actually a week from tomorrow. We have been trying for a baby for 4 years, it was kind of if it happens it happens because I have PCOS and I don't expect to get pregnant. But this past month or so I have really been trying. I don't keep up with my cycle because it is really out of whack. Now I'm trying to keep track, the last was at the end of Feb and lasted 2 weeks! I've been taking Pregnitude and prenatal vitamins, but still no cycle yet. It's getting so frustrating because I want a child so badly and I'm getting up there in age. And on my birthday, I signed up to attend an adoption class lol. One way or the other...Anywho, any other suggestions besides going to the doctor spending thousands?
