So past Tuesday i went to hospital for shortness of breath and palpitations they ran some test also a urine sample which then i was told if i was aware i was pregnant which i wasn’t but they did 2 tests both strong positive so after them finding nothing wrong besides being “pregnant”let me go home the next day Wednesday I decided to take a pregnancy test at home came out light positive i wasn’t to concerned i thought maybe my tests we’re cheap or hospitals are better at picking up hcg but Friday same week took another 3 all negative so I’m confused since i haven’t had any heavy bleeding what could have happened and what you recommend i do?
