Preeclampsia Screening

Hello mga mommies, I’m currently 12 weeks 2days and my OB asked me to do preeclampsia screening. Every visit ko kasi sa OB around 130/80 to 139/104 yung BP ko pero pag nasa bahay ako 113/81 to 118/81 yung BP ko. Lagi ako kabado pag pupunta sa hospital kasi di ako usually nag hohospital and first time mom ako. My OB said lahat naman ng lab tests ko super ok kaya nag tataka sya. Ang mahal din kasi ng preeclampsia screening. But im running out of time. Totoo bang until 13weeks lang ito? Baka meron kyong alam na place na mas mura and did you experience the same thing? Pano po ba ung procedure nito? Thank you in advance #firstbaby #firsttimemom #advicepls #preeclampsia
