I’m so scared.

Well, I was due on my period on Saturday, but it is now Wednesday and nothing has happened. I keep getting twinges but nothing like my other proper period pains. 

I know there is a chance I can be pregnant, but I don’t know what to do next. I’ve done the test you can do 6 days before your missed period. They BOTH come back negative? But it would be 2 weeks on Friday so I don’t know if I should do one then?

But I am so scared. I really do not know what to do

Can someone please help me?
