Uy, honestly dapat ka na magpatest or makonsulta ng doctor para sure, sis, hindi ko ma-say ng tama based lang sa kwento, pero ang spotting at delayed period ay kailangan tignan ng professional! I know maraming signs pwedeng mag-confuse, pero para sa peace of mind mo talaga, get a pregnancy test from any pharmacy or visit your OB, especially important dahil gusto mo talaga malaman. A few of my mum friends din nag-worry sa ganyan, pero naging clear agad after proper checkup, so alam mo agad ano next steps. Hang in there, and let me know how it goes!
