So ladies I'm 22 weeks. Have a low lying posterior placenta. Don't know whether that makes any difference. But ive just come off a 13 hour night shift. Im a support worker so spend the night looking after young people with disabilities and cleaning the home. For some reason since about 4 this morning I've been having a lot of pains. The only way I can describe the pain is like I've been riding a horse and everything I move or walk all the insides of my legs a bum are aching. Really hurts the. Feels like I'm really stiff. Just wondered if anyone else gets this? X
