IMPLANTATION BLEEDING or PERIOD?

Hi mga momsh! Seeking for your help po 😁 Just wanna ask lang po dapat today is my 1st day of period pero delayed nako ng 1 day. Usually po kase either 1day before or the day ang period ko pero nagkaroon lang ako ng kaunting spotting yesterday. Yung spotting na parang taghabol? Tapos yung color po is not really reddish at all. MagPT po ako tomorrow morning din. Thank you!
