Ilan weeks bago magpacheck up?

2 days delay po ako, and tested positive sa PT. Was wondering po when is the best time para magpunta ng OB? Note: I was pregnant too last month but had a miscarriage so I kinda know what prenatal care to do, like taking folic acid and eating healthy foods, and taking a lot of rest. Gumastos lang kase ng ako nung nakaraan, puro lang wait na magkaheartbeat, started doing transv at 4th week, and take meds and gastos sa transv at doc’s fee. Ano po wisest week na magpacheck up? Currently eating fruits, dieting, plus taking folic acid na.
