Eh, I've been there during my second pregnancy, so scary kan when your heart starts racing and you can't breathe properly. Honestly, what worked for me and a few of my mum friends was slow breathing (in for 4, hold for 4, out for 6) and just doing something grounding like holding something cold or focusing on one thing around you, really helped calm the panic down. But please lah check with your doctor or OB about what you're experiencing, because anxiety during pregnancy is serious and they might suggest some safe support for you, don't just tahan alone. Some of us also found it helped to talk to someone, whether it's our partner or a counselor, because keeping it bottled up only made it worse, and pregnancy hormones memang amplify everything. You're not alone in this!
