Aww, I know how scary this feels, especially when you're TTC! Spotting or bleeding baru lepas bersama memang boleh jadi normal (implantation bleeding, hormonal shifts, atau ada kecil kecil issue), tapi honestly for peace of mind you should check with your doctor ASAP, jangan delay, better safe than sorry, kan? A few of my mum friends yang TTC pun pernah experience something similar, some turned out fine but a couple needed proper check-up, so best lah go see someone who can do a proper exam or at least confirm your cycle dates.
