20 week freak out...is this normal?

FTM here. 20 weeks to the day. For a few days I've felt actual kicks, not just the fluttery (possibly gas) movement. It was consistent and strong the first couple of nights. Last night I only felt a couple when I laid down for bed. So far tonight I haven't felt any. I've been pretty sore, like I've done a bunch of sit ups. Is all this normal??

I'm not going to lie, lock down and bad weather has made it really difficult to do much moving around myself and I'm sleeping a LOT. Not to mention struggling to get anywhere near enough fruits and veggies since fresh produce is hard to get right now.
