Congrats mama, that sounds like quickening and it's totally possible at 17 weeks, especially if you're a first-time mom, some of us feel it earlier than others! The difference between cramping and baby kicks is that kicks usually feel like little bubbles or flutters that come and go, while cramping is more constant, so if you felt distinct little movements when you touched your belly, that's probably baby saying hello na. One of my mum friends felt kicks at 16 weeks and she was so sure about it kasi it was different from the cramping she had before, so trust your instinct, you know your body best!
