Hi, I'm not sure if I've missed the page relevant to this in my pg books, or if I'm just strange!

For the last two weeks I have been getting a funny sensation, and it was much worse when I went back to a very busy day at work yesterday. The lower part of my tummy feels very tight and goes very hard for about 5-10 seconds. The last couple of weeks it only happens once a day or less, but yesterday it was like every 10 minutes or so. I have an anterior placenta, so I only feel movements down low, except for the odd kick near my belly button.

Is this just my bub moving (doesn't feel like it, but what would I know LOL!) or something else? I was almost going to call my OB yesterday, but he's away ATM, so I thought I would check here first! TIA
