Ladies! I need help!!

Michela
Hi everyone. Looking for some answers! I had my IUD removed on November 13th, got my period on Novemver 15th until  November 22nd. My boyfriend and I are TTC. I have never been late for my period ever. I am very regular. My period was supposed to come today. I usually start spotting and bleeding 2-3 sometimes 4 days early. I have severe PMS symptoms too. Debilitating cramps and pain, diarrhea, vomiting, headaches, backaches, and sore breats. I get a certain discharge right before too. My boyfriend and I try to bd about 4-5 times a week. I did not get my period today. Like I said, I have never been late ever in my life. I haven't gotten any of my usual PMS symptoms, and spotting, discharge, or sore breasts. I went and bought a pregnant test today and tested and it came back negative. Is there anyway I tested a false negative?? I need help, answers, guesses, or opinions! Help! Please.
