Haven’t gotten my period 😳

Schertevear

My last cycle was May 7th and it’s now June 20th. I went to the doctor on the 1st of this month and I took a test and it said Not pregnant. Then I took a pregnancy test on the 16th of this month and it said Not pregnant again for the 2nd time 😔. My cycle normally comes at the beginning of the month but it hasn’t came. I need help Im not sure when I should take another test.

What do I do?
