Two types of movements?

I am 30 weeks today and I have been trying to track baby movements, which I find very difficult, especially as I have been very busy at work so sometimes the day just passes in a blur. It also feels like depending on the day the baby can be on two different positions. There are days when I can feel and see him pocking at my belly, like he stretches and drags . Those are my favorite because I can clearly feel him and it’s genuinely exciting. But then I have days when he is maybe facing the other way, if it makes sense?? I can still feel movement but is more internal, and when he is like that I get more nervous because I don’t feel his as much and also because when I do he tends to kick my cervix!

Anyone else experiencing something like this?? I should add that I have an anterior placenta.
