Ang first trimester check-ups ay usually monthly, tapos every two weeks kapag papasok ka na sa third trimester, pero it really depends on kung normal ang pregnancy mo or may concerns! A few of us dito sa group namin, nag-start ng weekly visits na around 36 weeks kasi approaching na ang due date. Best to ask your midwife or OB directly what schedule they recommend para sa iyo, kasi bawat pregnancy ay different at bawat clinic may slightly different protocol din.
