18dpo no AF

Ana • 1 👧🏽 , ttc baby #2 🌈

Hi everyone! I’m currently 18dpo with no AF. I do have super sore boobs & and some minor cramping. Tested this morning and it was a BFN 😔 I have noticed when I go to the bathroom whiteish/clear blobs of CM in the toilet. Is it possible I can still be pregnant at this point and showing negative on a test? Want to be hopeful that I’m still in but also getting to the point where I want to give up on trying to conceive our 2nd child 😔
