Hoping for some guidance

I miscarried twins at 6 week in December of 2013. July 2014 I had a chemical pregnancy. November 2014 I had another chemical pregnancy. I went to a fertility specialist in December and they did some testing and everything came back normal and told me to have fun and keep trying. I have used ovulation tests before, but finally splurged on the Clearblue Ovulation Predictor kit. This was my second month using it and I was 4 days late, my boobs hurt like crazy, I was super nauseous, but I didn't take a test because I didn't want to "know" and then just miscarry again. I thought for sure, this is going to be my time!! Well, I started bleeding yesterday so I'm not sure if it's just my normal period coming a little late or if it's another chemical pregnancy. I really don't want to know.

I just don't know what to do. I can get pregnant, but just can't keep the babies. Should I keep tracking my ovulation and peeing on those damn sticks every day or let it go, not think about what cycle day I'm on and try to just have fun? I am just so sick of this and so sad. Everyone around me is getting pregnant. My husband tells me not to worry and that our time will come. How do I keep the faith? Every day I go through a roller coaster of emotions.

What do you ladies suggest?
