I Ovulated (and on my own) !!

I tossed and turned all night thinking about my blood test this morning. I got up early, ate an English muffin and was there right on time. I was a little nervous because I had to be in the Winter Park office by 8:30 to open and Dr. Trolice always runs late. I got in about 8:05. The nurse was very sweet and said I'd have the results this afternoon. I thought about it all day. I did a Google search on backaches when I got back to the office and everything I read said it was an early pregnancy symptom. Great, just what I needed to hear! About 3:30 I called Dr. Trolice's office to get the results. Just then Chuck and a customer walked in so I couldn't really talk. The nurse told me I'd ovulated! I almost fell off my chair. I've never ovulated before. She asked me if anything had changed recently and I told her I've lost weight and I take Metformin. She said even a little weight loss will fix fertility problems. How encouraging!! I couldn't really ask "what next" but she said either I'm pregnant or I'm getting ready to start. I can take a home pregnancy test by the end of this week if I want to. But I feel like I'm going to start my period. I have cramps and my back is still killing me. Can it really be that God wants me to be a Mom again so soon after traveling this infertility road?? It's so hard to think positive and pray and hope I'm pregnant, only to start my period and be disappointed again. I feel like screaming to the world my news, and yet we are keeping this from family for awhile.
