Uy, mama, this is definitely something na kailangan mong follow up agad with your OB, hindi siya something na pwede i-DIY, okay? Your doctor needs to explain your results and what it means for you at baby, so please don't worry in the meantime, but do go back to your clinic para ma-clarify.
I haven't personally experienced this, pero I have a few mum friends who had confusing test results during pregnancy, at honestly, ang best advice is to trust your OB completely, they'll guide you properly. Sending you a hug, sis!
