Balakang pain

Hello mga mi! Im 35 wks and 5 days na as of today for some reason may stabbing pain sa balakang ko pag natayo or maglalakad pero pag nakaupo naman walang pain. Not sure sa cause and what i cna do to relieve lan. Super hirap po kasi maglakad. Parang may naipit ata or something 😥😥 #pleasehelp #firsttimemom #balakangpain
