What’s going on??

Period was due December 23rd and came on Thursday the 28th. I was taking multiple pregnancy tests and all cane back negative. We’ve been ttc for a year. This had been by far the worst period I’ve ever had. Constant cramping, diarrhea, no appetite, nauseous, and my bleeding stopped today. What do you thinks going on? Scheduled to see my ob Tuesday for normal checkup. I’ll definitely bring to her attention
