Possible yeast infection

So I’ve had a yeast infection before a while ago so i forgotten what it feels like. But i believe that I gotten it again. I just had sex for the first time in almost 2 years and without a condom. My period was also supposed to come on two days ago but it hasn’t yet. I am on birth control so my period is irregular.

Discharge is mostly a white creamish color, sometimes its pink(I’m guessing from blood). I have all the usual symptoms with cramps(not painful just uncomfortable and annoying).
