Im on the pill and have had my period since 2016, but two weeks ago I got my period early (on a tuesday) and it had only lasted a few hrs (5:00pm until 8:00am the next morning), I am having concerns about pregnancy but the test came back negative. Ive also been having spotting and nausea, light headed and tender belly and boobs, Ive also been feeling like once Ive stood up it feels like ive been standing for hours, is this normal? Should I buy another pregnancy test? Should I go get blood tests for pregnancy? Is this a pregnancy scare?
