Baby kicking cervix so early?

Just • 2 girls & baby girl no3 on her way 😘
I'm 16wks on Saturday and for past two days I have been getting that shooting sensation in cervix that I got with DD. My Midwife at the time with DD said its baby tapping cervix but then I was in third Trimester.
 Should I be worried it's happening so soon this time around??
