Hello po. First time ko po magbuntis kaya d ko po alam kung ok lng na mamiss yung schedule ng next check up na binigay ng OB ko(nung first check up). Delayed na po ng almost 1 month since umuwi ako ng probinsya. Bale I was supposed to have laboratory test (ung bc counts, tb test etc ganun). Tapos may nereseta sya dati sakin na vitamins (prevena yung name) pero tinigil ko midway kc napansin ko na parang d maganda pakiramdam ko after mag take parang sumasakit ulo ko and nahihilo ako. Your response will be much appreciated. Thank you in advance. *around 6-8 weeks pregy na po pala ako nung nagpacheck up ako for the 1st time tapos nasa 15 weeks na ako now*
