is this a yeast infection?

😎

I have no itching or any burning. i’ve had yeast infections in the past and would get super intense burning and itching. I did masturbate twice earlier so I believe this could be a mixture of cum and fertile discharge. just wanted a second opinion. the 1st and 2nd picture is the only 2 bits of stringy discharge I had in the opening of my vagina. it was stringy with a mix of like thicker creamy lotion type of discharge. 3rd and 4th picture is what it looks like now if I were to stick my finger in there now. not clumpy, pretty clear, maybe a hint of white.
