Help please

Amanda • Love being a mom. Have five kids now and expecting our final little girl. Our son Denver watches over us all.
I'm a mom of four and I really wasn't trying to be pregnant. My period has been all crazy lately due to stress. When it was late I didn't think anything. I however took this test and I'm worried it could be positive. Please help it's really faint so maybe no?? Should I retest in a couple days
