Hi ladies I'm 16 weeks pregnant and during the night I noticed I had pain in my left side down around my hip area but more to the front of my tummy rather than the side. The pain has been persistent all day and worse when moving and walking. The only way to describe the pain is it feels like a stitch that just won't go away. I'm not feeling unwell just really sore. Has anyone had this or any idea what could be causing it?
