Hello! I'm A 20 Year Old Female. I Just Recently

Hello! I'm a 20 year old female. I just recently moved from Virginia to Florida in May. I had my May period totally fine and normal but I skipped my period for last month and have yet to start my period for this month.. I should be scheduled to in a few days though. I'm not sexually active. I'm not on birth control or anything either. I have been on my feet more, stressed out, and eating not to healthy due to budgets but staying in the sun and way more active than I have been in Virginia. I read up on it and I saw these things can infact make you miss a period but I just wanna make sure I'm not freaking myself out. I feel completely fine and healthy otherwise!
Thank you!
