AF is suppose to come tomorrow.. 10/22

I have twinges of pain in my pelvic area. By now I would have flat out cramps telling me that I was pregnant. Last night laying in bed I felt like I had a someone sitting on my chest, making me short of breath. I have had many symptoms since we did the deed. I took a HPT this am and it was still negative!!?? With my last two babies I had taken one day before AF was due & It flat out said I was pregnant. I am getting super impatient:( If anyone has insight on this let me know!!
