Since this is your fifth pregnancy, your cervix may take longer for it to rise. For the CM, I've actually posted a post about this "waves of CM" which is normal for many pregnant women especially in the first trimester because our bodies produce more estrogen thus causing more vaginal discharge. Also, CM helps to limit number of microbes growing. I have lots of CM starting about week 8 and continues till now and maybe until my bub arrives. You'll just need to invest on lots of panty liners!
