Cervical position??????

Am

I'm 5 weeks and 3 days pregnant. About 4-5 days ago my cervix was VERY low and firm and open, then it went all the way up and has stayed closed soft and high, I checked it this afternoon and it was the same, then checked it this evening and it was about midway firm and open. Should I be concerned? What are/were your cervical positions in early pregnancy? Thanks so much ladies!💘
