I am 28w with my first and today have been getting some rather odd movements by Bean. Especially when I am sat at my desk, there are some rather sharp movements, almost like popping or sharp kicks, very far down. At one point today I thought I would get a foot sticking out of...well I imagine you can work it out! Just a good job I was on my own in the office as it took me rather by surprise 
I am presuming that this is just the latest crazy exciting development but as I think my DH and others would be a bit shocked, I thought I could hide behind the anonymity of MN!
