Conscious/thinking

Hello mga sis ask ko lang me and my husband is trying to conceive as in.. My last mens is august 12, 2019 sa flo tracker ko dahil 28 days ung cycle ko expected ko is sept 9 meron n dapat ako mens kaso wala pa..nag pt 3 times but negative.. I am taking nga pala fern d , ferd d active and milka.. It is possible ba buntis ako? O should i wait for weeks then tsaka ako mag PT.. kung titingnan kasi almost 4 days palang ako delayed.. Sometimes i feel n parang nasusuka parang nahihilo, breast ko nmn ndi masakit pero parang mabigat.. Ayaw kong umasa hope meron makapag panatag ng loob ko.. I was diagnosed pcos then pala 2015 pa..and also na ectopic pregnancy din ako 2015 pa din un.. Thanks mga sis
