Scared to test!

Ana
So we've been trying to conceive for 4 months and now I am late 5 days and I am very very regular.. I'm never more than one or two days late. I'm scared to test because I had miscarriage a year ago and scared it can happen again. I have that feeling that AF is coming but nothing at all and it's not a constant feeling and just comes and goes. I'm just really scared
