Af late

Sheyla
So I'm on CD 28 my period is very normal never been late unless am pregnant. Normally my AF come during CD 25 to 27 always. I already took to test both BFN. Not sure if I need to wait a little longer. I have been TTC for over a year and I start my first clomid cycle on July 23 to the 27. Also I have a lot of nauseas feeling bloated a little of constipation cramps and other symptom. I'm just very anxious don't know what to do if waiting or do another test.
