Mucus in Urine TMI

Hi, I changed birth control pills last Oct 17 to Diane pills.

Also my OB prescribed me to take neopenotran for my fungi and bacteria in my vag.

I only use it one time last Oct 15.

Is this the result of not using for straight 7 days?

Because I only use once neopenotran.

Or this is because of Birth Control?

Or something more serious?

Been observing and this is my 3rd day having this.

Every 2nd urine of my day always has mucus or white tissue but on the first right after I wake up and after the 2nd urine.. my urine is clear though out the day.

((Did not have sex for 2 weeks now so I guess not pregnant))
