Ay, that can be really stressful, spotting after a negative PT usually means your period is finally coming, pero kailangan mo talaga ipatingin sa doctor para sure, lalo na kung 2 months ka nang delayed kasi pwede pang may iba pang dahilan like hormonal imbalance or stress, and kailangan nila i-check properly. A few of my mum friends went through something similar, and isa sa kanila nag-turn out delayed lang talaga dahil sa stress and thyroid issues, kaya mas okay kung may checkup na agad para makita kung okay lang or may kailangan i-address.
