Sayang, this is something you really need to discuss with your doctor or OB-GYN at your next checkup, they'll give you the right guidance based on your condition, okay? I know it's worrying, tapi jangan stress dulu, placenta position boleh berubah lagi, especially at 25 weeks you're still early. A few of my mum friends had similar situations and it resolved on its own masa they progressed. Just follow whatever your doctor advises, rest when needed, and avoid heavy lifting. Take care!
