Am i pregnant

Hi I’m 27.. Today makes it the 9th day I missed my periods..last period started 20th aug.. 25 day regular cycle this is strange because I’m very regular but anyhow I took 3 Hpt but all were negative. I have no morning sickness but very bad lower back pain I’m hungry most of the time

I have slight white discharge and a bad cold. If I do test positive this will be my 2nd pregnancy but my 1st baby.. my hubby is too excited for a baby but I’m worried since I’m not sure what to do next? Please suggest.
