Please advise...

So back in March when everything started closing with the virus, I had to move back in with my parents from college and finish out my sophomore year online. I could tell that my health was slightly decreased after this, but I chopped it up to the stress and anxiety of moving back home.

On May 12th I had unprotected sex, but I have been on BC. To be on the safe side I went to the store to get Plan B, but the store was out of most emergency contraceptives...sand since I live out in the middle of nowhere I could either drive 2 hours, or order it online. I ordered Plan B online and took it when it came in on May 15th (with in 72 hours). I felt nauseous that night, but it was bearable and that is one of the side effects.

On May 20th I started my period (but it came early, I’m assuming because of the Plan B).

Yesterday, May 22nd I realized I didn’t take my BC on the 21st so I took the pill that I missed and the one for the 22nd.

Around 4am on May 23rd I felt super nauseous and went and sat down by the toilets and have thrown up 5 times in the course of 3 hours. I have taken small sips of water to try to help me stay hydrated, but cannot keep anything down for longer then 20 minutes.

Since my period came, I shouldn’t be pregnant...but I’m not at the 2 week point to take a test for the best results. Is there a chance that I could be pregnant? Or an underlying health condition? If a health condition, what type of doctor should I try to make an appointment with?
