No period in sight and negative tests

I had a miscarriage in November got my first cycle in January 20 days after my miscarriage. Then 36 days to my next cycle feb 16 now on day 42 and nothing I took a test last week that was negative and one this morning negative also. I was praying I ovulated late and would get my positive today. This is so depressing all I want in the world is to be pregnant again.
