Hello po! Nakikita ko ang iyong concern, at honestly, ang combination ng symptoms mo, nausea, spotting, cramping, white discharge, at ang sensitivity sa smells, ay worth checking with your doctor na talaga, lalo na kasi may withdrawal kayo and you're tracking your cycle carefully. A few of us mums sa group namin din nag-experience ng delayed period with spotting at first, pero ang best way talaga to know if it's pregnancy or something else ay through a proper check-up or blood test, hindi lang pang-peace of mind, pero important na ma-rule out other things din. Mag-PT ka na rin if you want, pero kung delayed ka ng ilang days na, mas accurate na ang test results ngayon compared waiting pa. Let your doctor guide you on what's happening, kasi marami pang possibilities at kailangan ng proper assessment!
