Mama, please go to your OB or health center right away, ha, 3 months delay with positive tests then negative is really something they need to check properly. Hindi kami dapat mag-guess dito, kailangan mo ng actual ultrasound and blood work para malaman kung ano talaga ang nangyayari. About the lump you're feeling, that also needs a doctor's hands-on check, hindi basta puwedeng i-assume. A few of my mum friends thought something was serious pero it turned out manageable once they got proper checkup. You deserve to know what's going on, so please don't delay the visit, okay?
