Random pregnancy question.

So I'm 5 weeks and 4 days today. Around the time I found out my skin got terrible. Awful cystic acne and zits all over. Hair looked dull and just gross. I was extremely bloated and felt awful about myself. I noticed yesterday my hair is shinier again, my skin is almost 100% clear and quite Dewey and I even seem to have lost weight??? Wtf. Is this type of external physical fluctuation normal in early pregnancy?
