Yellowy, mucusy CM

Lucille

I’ve been getting this type of CM and mild cramping for 5 days now. I haven’t had my period since my son, he’s 16 months. I’m just wondering if it’s a sign my period is coming back or a possible pregnancy. I took two tests and both were negative! No spotting or anything, just this and some cramping. The cramping only lasted 3 days. No itching either.
