AF still no show

Laura • Thu, Jan 30 2014 • One son 11 years old had Ectopic and lost my baby on 12th Feb2014 ❤️ 2nd ectopic baby lost Nov2014, expecting Feb2017

So I'm 2 days late, negative test last Friday (24th) maybe still too early. I've had sharp ovarian pains occasionally for past few days and today I've noticed a creamy discharge. Should I test using the clear blue digital that clearly says the words pregnant and how many wks??
