So confused!!

I've had yellowish/greenish discharge on and off for a while now but I've always shrugged it off as it hasn't been constant. However, the last 2 weeks I've had an increase in discharge and it's been yellowish and stretchy. It doesn't have a bad smell, it smells quite sweet sometimes or doesn't have a smell at all. When I've googled about it, some say bacterial vaginosis, some say trichomoniasis, some say it's normal if there is no burning or itching. I also don't have burning or itching. Has anyone else ever experienced this? I am also 11 months postpartum!!
