Aiii, I feel you, tension gila bila macam tu! Kalau test kadang positive kadang negative, normally means hormones still too low to register properly, so best thing is tunggu another few days then test again with first morning urine (paling concentrated), atau boleh straight pergi clinic ambil blood test, sure clear answer dapat. One of my mum friends had the same thing, turns out she was pregnant but terlalu awal test, jadi berulang kali confusing je; another one ternyata delayed cycle je sebab stress. Either way, kena tengok doctor lah untuk confirm, tak sabar pun nak tahu, right?
