More frequent urination while on Yasmin?

I starter taking Yasmin (drosperinone+ ethinyl estradiol) a couple of days ago (since Wednesday) and I've noticed I've been needing to pee more frequently the last couple of days (about once every 2-3 hours). I did see online that drosperinone is structurally similar to spironolactone, a diuretic, but nowhere mentions frequent urination as a side effect.

I was worried that I could be pregnant since I had sex a little over a week ago and I had a really bad bout of nausea the night I took the first Yasmin pill. However, at the time I was on the last sugar pill of my previous OC (Micronelle) and I haven't felt nauseous since, just some tightness of my throat. Additionally, I took a pregnancy test and it came back negative, but I'll take another one next week just to make sure.

So with the preamble out of the way, my main questions are: 1. is it common to pee more frequently on Yaz/Yasmin/Slinda? 2. Is it possible (or likely, ofc pregnancy is ALWAYS possible) to ovulate on the last days of the sugar pill if your period is only 5 days long and you didn't bleed on the last day?

Thank you guys a lot - I spent a lot of time lurking while choosing what BC to go with and it's scary going on it but having a community like this has made it less stressful.
