Green chunks in discharge but no smell/soreness?

I have been to my Dr & spoken to my midwife about having these light green chunks in my discharge but because it’s not sore & no smell etc they were literally no help! She said I could get canesten pessary because I’m pregnant (17 weeks) and see if that helps but that they don’t do anything if there’s no soreness or itching. I read the description on the canesten and it doesn’t say symptoms are anything like what I have (which is basically nothing but the lumpy discharge) so I’m not sure what I should do or if that’s it and I should just ignore it as my dr isn’t concerned? I’d always thought it to not be normal. Anyone that’s had similar or may know what would help/any advice would be great thanks.
