I am 44-years old, my period would come every 28 days and last for 7 days faithfully. July 15th was the last day of my period and I haven't seen one since. I am bloated, sore breasts, suffering morning sickness, headaches and having problems sleeping. I have taken several pregnancy tests and all have given me a negative result. When I was pregnant with my daughter the test read negative so a blood test was necessary along with an ultra sound to determine I was pregnant. Could I be pregnant again?
