I'm 21 weeks along and definitely feel like my belly just popped over the past few weeks. But the downside is some fierce round ligament pain last night! At least I think it was- this is my first baby so I don't have anything to compare to. I had shooting pains down the lower left side of my belly and into my groin and lower back for about three hours. It took my breath away! I've had the odd twinge when I sneeze or cough, or rollover too fast in bed, but nothing like this. Any other mammas out there suffering from this? What do you find helps ease the pain?
