Symptoms I'm having:
- Burning when urinating (vulva area)
- Swollen, tender (inside and out)
- Yellowish slightly watery/tacky discharge
- Small ulcer like/ canker sore looking bumps around a the vulva. (Recently started)

Extra info: Sept 7th my boyfriend of a year ejaculated in me. I took the generic, plan B on Sept 9th. On sept. 13th I got my wisdoms pulled and took 7 days worth of amoxicillin (3x a day, finish the antibiotics on sept 22). On the 17th I started to feel like I was having a uti. I began my period on the 18th(the next day). The UTI like symptoms was going on and off until I decided to see a dr. on sept 21 because it started to burn my vulva area when I urinared. He said I my results came out negative and that I possibly have a vaginal irritation. Over the next 2 days I started in extreme pain. Burning when urinating, swollen, slightly itchy, Tender and sore vagina, and now I have these small like ulcers. That remind me of canker sores in the mouth. What could this be?.

Did the doctor prescribe something?

Jus medication the relax my blatter. Yesterday I called crying to my obgyn who got back to work from time off do to sugery. She said sounds like yeast infection and prescribed me Diflucan over the phone and emailed it to my pharmacy. But I didn't see her in person. I'm 23 and never had any issues with my vagina before so I don't understand what's going on.

Amoxicillin is notorious for causing yeast infections. Yes, it does sound like yeast. Take the diflucan as prescribed.

I took it immediately, it's been over 24 hours and I've haven't noticed any change. Also, are these small canker sore/ ulcer normal? Or do I possibly have a severe infection?

You may have to take two courses of diflucan. In the meantime, you can get Monistat over-the-counter.
