Low placenta

Hey mummies, during my 20th week check up I was told that I have low placenta. I’m at my 23rd week now and since then I’ve always felt pain/sore around my upper vaginal area. Sometimes, the pain would go down to my thighs too. Pain is still bearable tho. And when my baby kicks, I feel it in my vagina too. Was wondering if it’s normal since I have low placenta?
