Hey, I took a hpt on the day my period was due, it was bfn :( 
​It's the third day and still no period.
​My cm switches between watery and creamy.
​Today I'm emotional and fatigue with a headache :( but still have the usual ovary pains I get but they are very mild than they usually are.
​Should I test again?
