Changed city and cycle and everything has changed

Hello not sure how to frame this but since I have changed cities my cycle has gotten irregular and my hair is falling a lot. I have also never got pimples but now that’s also coming like pus filled also periods whenever they come they hurt more and I am tired for long time and pms is crazy and I am very conscious about my body it feels very bloated even on non period days. What should I do last when I checked I did not have pcos should I take birth control but I have heard it makes you gain more weight and break out and I don’t want that or is there some home remedy or should I consult a doc
