When you first start feeling a baby move, it is not uncommon for it to come and go in spurts. The baby may be facing your back these days so you can't feel the little kicks you felt last week when he was facing your front. At 15 weeks, I wold not be worried. It isn't until after 20 weeks that babies start to become more predictable and it isn't until the beginning of your third trimester that you begin to really notice their sleep and wake patterns. I wouldn't worry about it. You can call your doctor for reassurance, but it is still early to expect predictable movement. Early on, I remember having days that I could feel baby all day and then the next day wouldn't feel a thing. It is normal early on.
