Hi...I had my period ending a week ago. 4 days later I started to experience dizziness , stuffy nose, slightly tender breasts, lower back pain , and intense abdominal pressure. Home pregnancy tests all come back negative. I ve had 2 sexual partners this year. I am uninsured so Dr visits r expensive. Worried I could be pregnant, have an STD , or an infection. What should I do? Wait to take more HPTs in a few weeks? THANK YOU FOR YOUR HELP.
