Negative Results

Had pregnancy tests about 3x this month, 2 were negative and the last one was invalid. I really want to get pregnant and I feel frustrated kasi di ko pa din makitang positive ang result. Will undergo transvaginal ultrasound the 1st week of Nov ? Besides, may naffeel akong kakaiba sa tummy ko, what u called - quickening. I'm not sure if un na nga un since 2 and a half months akong delayed.. Sana meron na. Cheer up niyo ko ka momshie ??
