Turns out I have a bulging disc in my back! It's referring pain to my pelvis. I had this issue at the end of my last pregnancy after I fell over and it was bad post birth as well. So I'm essentially on bed rest (no sitting/standing/walking) for the rest of the week with exercises to do! Not sure how I'll go resting with two small boys but they have today and tomorrow at daycare so hopefully once the inflammation subsides it will be better!
