Help! My Oncidium pollinated by itself what do I do?

[KristinClarke]

So I was looking at my lovely Oncidium Catatante and noticed the stem of the last flower on the side shoot was swollen as was the ovule. Didn’t know for sure what was going on but I had my suspicions which were confirmed on the internet🫢. Since I hadn’t planned on this “pregnancy” I’m not sure what I should do about it. I know it can me very difficult to grow from seed so I’m a little scared 😱. Does anyone have any advice on what I should do?
Thanks so much to anyone who replies,
Kristin
PS Just looking at this plant again and the blooms on just one of the side shoots are very strange, multiple lips and other oddities like that. Why does this happen? Especially since all the rest are normal!
