Hay, alam ko yan feeling, I had it too after giving birth, parang ang sakit talaga ng pelvic area for weeks, pero honestly, one week pa lang kaya there's a good chance it's just normal postpartum soreness from labor and delivery (nagsuffer talaga ang muscles and ligaments mo). Thing is, pelvic pain can range from totally normal to something that needs checking, kaya if it's not getting better or mas lumalaki pa, I'd really suggest checking with your OB just to be safe, could be anything from muscle strain to infection, and hindi ka makakatulog ng mahimbing kung worried ka eh. In the meantime, rest as much as you can, paracetamol if you need it, and try not to overdo the physical stuff. Hoping it eases up soon for you!
