20 days late and 3 negative tests and I still think ...

I'm 32 years old my period was always sharp never delayed. Now it's more than 20 days late. I did two tests of pharmacy and one of blood because I thought I was pregnant the three gave negative. I still think I'm pregnant, what should I do?
Expert answer:

First stay calm and quiet and then look for a gynecologist who will conduct the investigation for the other causes of menstrual delay. If you are in doubt about the exams, you will continue to have doubts as to why this can actually happen (you may be pregnant even with negative exams).
