TMI discharge. Pregnancy? Normal sometimes?

All other discharge is normal but I’ve gotten this randomly off and on all day. No smell. It’s not a yeast infection because I’ve had one before and know how they feel. I’m on day 19 of my cycle.

My husband and I typically use vaginal films which we did two days ago when we have sex but we had random unprotected quicky sex on day 14. I’m 10 months postpartum
