Sayang, these are serious conditions and I'm concerned for you, please see your doctor or go to the hospital right away if you're experiencing symptoms like severe headaches, chest pain, shortness of breath, or swelling. Don't wait, okay? I haven't personally gone through this, but a few of my mum friends have had pregnancy complications and they all say the best thing they did was get checked immediately, early care made such a difference for them. These aren't things to manage at home, darling. Your health and baby's safety come first always. Is everything okay with you right now? Sending you a tight hug.
