Scared!!

I just turned 40 this month and I had my first miscarriage in March of this year. Now I am almost two weeks late with my period and I have all the symptoms of being pregnant. However I am so scared to take a test because I don't want to have another miscarriage.  Am I just being paranoid? I keep pushing back taking a test until I am further along and still no period.  Should I just take the test? According to my last period. I am about 6 weeks and this is how far along I was last time when I lost the baby.
