I gave birth 2 days ago and have been doing very well physically. However I just went for a 2 minute walk which includes a staircase and since I've come back I've developed an excruciating pain in my stomach especially on the right side. It literally feels like someone is squeezing my insides together. Anyone have any advice? Should I don't triage or GP? My baby is going to need changing soon and I'd getting grumbly but I can't stand or walk without being in alot of pain
