Dicharge, is that a yeast infection?

Been to a gynecologist months ago and said discharge like this are normal. I’m still not convinced and took a new appointment for tomorrow. I would still like to know if one of you girls already had this and what do you think it is. I don’t have burning sensation, sometime it’s itchy but not always, no bad smell (except after a whole day). I have vaginal discharge 24/7 and I have to change my slips twice a day. As you can see in the photo (tmi sorry) it’s pale-yellow and thick.
