I am 3 days late for my period, currently have Bronchitis as well. Went to doctors two days ago, they did pee test and it came back negative. So they did chest X-Ray. I'm prone to getting bronchitis and it doesn't normally delay my period. But tomorrow makes 4 days and I've had light cramping like my period is coming but nothing. And I keep getting this feeling like my period is starting and I run to the bathroom and it's just heavy white discharge. We've been trying for a baby for 4 months now. Thoughts??
