Sad. And concerned

So my husband and I have been TTC since October. We lost our first baby due to miscarriage in July of 2014. I was hoping to find out I was pregnant for Christmas. But, AF showed up this morning after being 6 days late. I want a baby so bad and seeing all these positive test post makes me sad. I had a d & c in July 2014 and also went on bc. I ended my bc July of this year. I'm a little worried that I'm not ovulating. I have a doctors appointment January 6th to see if everything is OK. I'm praying that I am able to have kids. I would be devastated. Trying to stay positive and faithful. I know my God will provide. Just hate the waiting game.
