worrying too much with non movement?

Marea
Hi guys, 
Just wondering if anyone is like how I'm feeling. 
I am now 17+5, I felt baby flutters at around 14 weeks, especially after my bath most nights, and laying down. 
These 3 days, I have felt nothing. I called my midwife, and she said it's surprising that I felt anything so early, and not to worry, I've got 3 boys, and had one stillbirth. 
Am I worrying unnecessarily? 
I have drank cold juice, poked my tummy, lay on my front, still nothing. 
Could baby be hiding? 
Thanks. X
