Tightening/pulsing feeling?

Draven
Hey fellow moms! I have been experiencing this extremely weird sensation when I lay on my left side. It feels like my belly is tightening and then is followed by what feels like a rushing pulse and a STRONG kick. Is it just her moving and feeling it more than I am used to(my placenta is anterior) or is it something to bring up to the doc at my appointment tomorrow? It almost tickles, but is definitely painful. Similar to hiccups but a faster sensation. It makes me not want to lay on my left side, she doesn't kick me like that when I lay on my right. Thanks for your help!
