Ang irregularity ng periods ay common talaga, lalo na if stressed ka, nag-diet, or may hormonal changes, ang spotting in between ay pwede ring nangyari dahil sa hormonal fluctuations or sometimes implantation if may chance kang pregnant. Best talaga na i-track mo for a few more months para makita ang pattern, pero if worried ka or nangyari ulit, mas safe na consult your OB kasi sila ang makaka-determine kung normal lang hormonal shifts or may something else going on na kailangan check.
