26 weeks with constipation pain

Gina

So noticed i havent pooped in 4 days or if i did it was very small pebbles. When i get constipated i get this sharp cramping spasm in my right side but now the achy feeling is higher. Not sure if this is related but i have a tingling in my inner thigh radiating from that area. Does anyone have any advice for the constipation its never been this bad.
