It’s 4 days before my period is due and I just been feeling lightheaded and super tired basically having the same feelings I had back in October when I was pregnant and we decided to take one of those HCG tests (bc all we could afford atm) and I was watching the test as soon as I peed on it and I swear I saw the faintest line ever appear ASAP, i thought my eyes were playing tricks on me so I had my partner take a look and he saw the same thing but now it’s disappeared.. is it bc I’m too early, those tests don’t detect before missed period orrr false positive?? I’m just super confused lol
