Increase and yellow discharge 38.2 weeks

So I’ve been having a big increase in vaginal discharge and the color has changed to yellow used to be clear in 38 weeks and 2 days and I’m not really sure what todo I have heard yellow discharge can be normal as I had had it before without an infection but just this close to delivery I want to get it checked because I’m having so much discharge I don’t have any other symptoms and if I did it would be hard to tell because at around 6 months I realized when I was convinced I had an infection but all swabs came back I didn’t I found out I had a horomonal issue that’s causing me pain and swelling and discomfort so if I had an infection it would be hard to tell the symptoms apart so I would like to just get it checked But today’s Sunday and tomorrow is a bank holiday so I prob won’t get to my doctors office till Wednesday or I’ve an appointment with docs in my hostipal on Friday would use recommend getting down ASAP on Wednesday or waiting till Friday ? Did any of use have sudden increase and change of color of discharge around this time ?
