Miscarried last month

I found out I was pregnant on Feb 19th 2014 I was 5 weeks , well the 25th of Feb I miscarried and here it is march 25th my period should've started today but hasn't and I'm having the same symptoms I did when I was pregnant a month ago..I'm praying and hoping that IF I am pregnant I don't lose this one cuz I can't deal with a 4th miscarriage in a matter of a yr and a half
