Mama, please go to your OB or the nearest hospital/emergency clinic today para ma-check agad, bleeding in early pregnancy needs to be assessed in person, kahit hindi malakas. Hindi ito pwedeng i-wait lang until March 4, okay?
I know this is scary, but your doctor needs to see you now para ma-monitor properly at ma-rule out anything serious. A few of us mums have gone through bleeding in early pregnancy at naging okay, pero kailangan talaga ng proper check-up hindi lang online advice. You're already on medication and may scheduled ultrasound, which is good, pero the bleeding + your worry deserves a doctor's eyes asap.
Sending you hugs, go get checked ngayon na.
