Thus far I have had a fairly uneventful pregnancy and not a very painful one either. However, I am now into week 32 or more - lost count, but I am due in mid June - and I have new sensations that bother me. I find that every once in a while a very casual gesture can send a twinge of pain down my back. For the past few days I have what feels like a pulled muscle on the left hand side of my abdomen. Laughing, sneezing, blowing my nose or flipping over while swimming can make it worse. Is this something I should expect at this stage of the pregnancy or do I need to see my doctor? I would be most grateful for any advice.
