Not trying to conceive pa po, so pls help, and answer 🥺

Regular po period ko from 28-30 days narating, ngayon 31 na wala pa rin and ito lang ang meron. Nag contact po kami ng partner ko, nung 27th day ko, kasi akala ko darating na rin period ko, pero wala pa till now. Ano po kaya ito? Delayed lang po ba ako? Pls answer. #advicepls #pleasehelp
