Pregnant or Stressed

Hi Glow Fam! So recently I started going back to school to get my bachelor's degree in another country. before I left my fiance decided to have sex every day and we used a condom and everything was fine. then a hurricane happened and my country is a mess and my best friend died and my fiance is going back to England and my other best friends are also moving away and there's no light or water on my island and it's stressing me out. But I'm a couple days late on my period. my boobs are heavy. I'm bloated. And my back kills me. I don't know if it's late cause I'm pregnant or Stressed and I don't want to be pregnant right now. between class and all what's going on where I'm from I'm worried that I might be pregnant and it stresses me out some more and if it is in fact stress then it might never come lol. What do you guys think? it's been a month since we had sex so should I take the test?
