Hi... My husben and I would to have another child, would had sex on the day that I was ovulating and know I'm 10 days late. I've been bloade and cramping and sometime nausea. And know I getting hungry around 2am. I've taken 3 HPT and there all negative. Could I be pregnant? Can someone help

Yes, the pregnancy tests could be incorrect.

The next step is to see a Physician.

It's less likely that you are pregnant if you had intercourse on the day of ovulation. It's better to try a few days prior to ovulating.

Take a HPT using first morning urine to be sure.
