Pregnant or not?

Sandra

I'm so confused. I got 2 obvious positives on clearblue rapid detection at 13dpo with afternoon urine! I then tested with a digital on that same day and then again on 14dpo which is meant to be first day of my period(this morning) and they were both saying "not pregnant". What s going on? If I'm pregnant shouldn't I have had a positive clearblue digital test by now?
