Sonogram

Hey Mommas, so today I went to my Sonogram app and was told baby A is smaller then baby B, they want to keep a close eye out. So now my app are every week. I also am 28 weeks but was told to treat my pregnancy as though I was 8 months already ...he said I can go into labor any day, min ...I'm really idk scared. These babies aren't getting enough blood flow to them so keeping a close eye...any other Mommas out there with something similar going on?

Also my feet feel like I have pins and needles at them ...clues to as why? I see my OB Wednesday...
