Could I be pregnant ?

Hi,

So, my last period was on the 10/8/18, so I assumed I would be on my period by now, 13/8/18, but every time I feel like I coming on, there’s nothing there. Few mornings I have woke up and it’s there’s been like a light pink when I wiped, (a tiny bit) so I assumed it coming but that’s been 3 days now.

I have Lower back for about 5 days straight now, headaches sometimes and in the morning my boobs are so heavy and sore.

Should I wait another week to see if it comes or take a test? I’m scared to get my hopes up after I had a miscarriage at the start of the year.
