Eh congratulations! Double line yang semakin pekat tu memang good sign, means HCG levels rising nicely! Tapi jangan lupa pergi clinic/klinik untuk confirm dengan doctor dan start prenatal check-ups ye. October baby, that's wonderful! A few of us mums, we always say that first positive test feeling is the best, enjoy it, but do get the professional confirmation soon so you can start planning properly. So exciting!
