I have been experiencing a dull pain on my ribs and hip area. Thought it was cramping but tonight I notice these veins going down my side from my ribs to my pelvic region. I pressed on the vein and sure enough that is exactly what has been aching! Tried to google it and the only thing that pops up in spider or vericous veins which it is neither. Chalking it up to another weird pregnancy symptom!
