I really feel you on this, carrying twins at 33 weeks is no joke and you are honestly doing something incredible even if it does not feel that way right now. The swelling, the breathlessness, the pelvic pain all at once is so much for one body to handle, so please be kind to yourself and rest as much as you can. You are so close to the finish line and your babies are lucky to have a mum who has carried them this far through all of that.
