My period last month was three days late and only lasted four days. It was very light. I only used panty liners and rarely had anything on the liner, just pink blood when I wiped. I normally have a very heavy flow as well as clots. I had a stomach virus right before my period last month and became dehydrated. I thought maybe that was why it was light. IDK. Now, this month, my ovulation is late. I usually have heavy EWCM, but nothing. I even did an ovulation test and nothing. Thoughts???
