ASAP! Help please!

Karey
7 days late for my period, now lightly spotting, and had a negative test. What should I do:( I had a miscarriage a month and a half ago but spotted after that aswell.. I also had unprotected sex after the miscarriage. Plus I'm peeing ever 30 minutes, plus hungry every 2-3 hours.. and I'm super moody and experiencing hot flashes and morning sickness
