Anyone get this cm and still be pregnant?

Jessica

So for some reason ive been noticing the last couple months I get this in my cervical fluid and heartburn (which I know the heartburn part can be a sign of pms or pregnancy). Anywho I am 8dpo based on BBT and 10dpo based on ovulation test. I’m nervous this is basically my body telling me once again my period is coming. Anyone get this in their cervical fluid and still be pregnant:(?
