Period 17 days late so far!

Hi girlies! I need help please.

Let me start off by saying I’m a Virgin. I started my last period on September 23rd and it looks like I missed this period bc it’s already November 10th and there is no sign of Aunt Flo.

On September 22nd I had a little bit too much to drink and I cannot fully remember the night. However, I did get my period the next day....

Like I said, I’m a Virgin and ever since I started getting my period my cycle is pretty regular and I’ve never had any problems with it. I don’t take any birth control either. Right before my last period I also got a yeast infection, which is super odd bc like I said, I’ve never really had any issues down there.

What should I do? What is happening??? Can alcohol affect your cycle? Can veganism affect it too? Ahhhhhh

I made an appointment to see an obgyn next week.
