Hay nako sis, I haven't personally experienced exactly that combo but a few of my mum friends did mention tingling sa shoulders and neck during pregnancy, usually kasi ng posture changes at hormones, pero ang hilo na kasama nito, that's something I'd really ask your OB about agad, especially kaya you're already 3 days in! Could be circulation, could be something else entirely, pero better safe than sorry lalo na may kasamang dizziness, okay? Preg brain and hormones can make us overthink pero trust your gut if something feels off, call your doctor or swing by the clinic, sis!
