No signs of AF...

Alright ladies so AF is due Friday but there has been no signs of AF yet. No spotting no cramping. My husband and I have been ttc for almost 2 years. I had a chemical in October. After my husband and I started trying again this month, about a week later I had nausea, extreme fatigue, swollen tender breasts and today I noticed my veins are more visible and popping out of my breasts. I've been crying over stupid stuff like today I cried bc I couldn't go grocery shopping. I have taken multiple tests and they are still negative. What should I do?
