Did you mean can you get pg while creamy cm is present?
The super fertile cm is egg white cm (EWCM). It really resembles egg white and will stretch pretty far before breaking. Creamy white cm usually of occurs after O and can last a few days. A lot of women here have had creamy cm, yellow
It's harder for the sperm to travel through creamy CM than the watery/eggwhite kind, that's what the latter are considered "fertile" CM. However, I had a cycle in the past, where I though I only had creamy CM at O time, but an internal check by my RE showed that there was in fact stretchy CM up inside the cervix...so you might still have it, even though you're not seeing it. Best of luck this cycle!
