baby movessssss

I just am freaking out, like I felt her poke my belly around 16 weeks, 2 days, and 15 weeks, but I am now 16 weeks and 6 days, and I haven't felt her move not one bit, and I always have small cramps not bad, but it's just worrying me, everybody says not to worry because their so tiny right now, but I've had 2 miscarriages in the past, it just really freaks me out. I don't have any symptoms at all either, just pee some what during the night and day, and minor headaches...
