How Long Should I Wait to test?

Af has been pretty regular due to my PCOS. Even after the removal of my BC ParaGuard....I have had 2 regular cycles in October and November.....

I traveled to see my husband on December 15th and from the first night we have been TTC....I was due for AF on the 24th and still NO SIGN....took a test in night on 26th that was a BFN.

I have been experiencing dizziness..nausea...tender breasts...minor cramping (not like AF cramping)....sleeping a lot more...and VERY EMOTIONAL.... Many of these I only experience when pregnant.

How long should I wait to retest seeing im 5 days late?
