Kick counts? 😒

Trying not to overreact and leave work for no reason but I’m a FTM and I’ve never really had to worry about movement before since my girl is usually active from the time I wake up to night. I’m 30 weeks and started counting kicks after being up for a little while when I noticed I hadn’t felt the nugget yet. I’ve had breakfast and some orange juice to wake her up and have only felt 5 kicks in about an hour and 45 minutes. Am I overreacting? I’ve never had to pay attention before because she’s so active and she’s usually kicking like crazy around this time. I’m cramping pretty moderately in my back and having the occasional BH. Should I call the doctor or am I being silly? 😢
