Honestly mama, implantation bleeding is usually very light spotting lang, like a few drops or light pink discharge, tapos mabilis maubos, hindi katulad ng regular period na tumatagal ng ilang araw pa. The timing din matters kasi usually nangyayari siya around 6-12 days after ovulation, so if mahaba na ang bleeding mo or medyo heavy, mas likely period na yan instead. Best thing to do is take a pregnancy test in a few days or check in with your OB para ma-confirm na talaga, lalo na since you're TTC at excited kayo! Praying for good news sa'yo!
