FADING POSITIVE PT WITH EMPTY ULTRASOUND

I tested positive for how many days, tapos po nagka brown spotting ako, akala ko implantation bleeding. I tested kaninang morning, faded na ang PT ko, nag worry ako kaya I visited my OB agad, nag UTZ sya tapos wala naman kaming nakita. As in clean na matres. May nararamdaman pa naman akong sore breasts at medjo nauseous ako. Is it too early? Huhu. I had miscarriage last November kaya po sobrang anxious ako. 😭💔 #pleasehelp #pregnancy
