10 months pp... discharge?

Hi! So my little girl is almost 10 months. I had my period the end of July and haven't had another yet. Which I know can be normal! But I've been having so much eggwhite discharge! Is this normal? Has anyone had this type of discharge for several days? It has no odor or burning etc. My husband and I did have unprotected sex this month but I took a pregnancy test 4 days ago and it was negative. I've also been having slight cramping. Maybe my period is trying to come 🤷🏻‍♀️ Any thoughts?!??
