Missed Period Help

Hi y’all! I am 25 days late on my period this month and freaking out! We always use protection and most times he pulls out with the condom on. None of our condoms have broken. I tested at 15 days late and had 2 negative tests. I’ve experienced dry nipples, minor headaches, and discharge that has a strange odor to it. I traveled for Christmas, had changed my sleep schedule due to being back in classes, and have lost about 4 pounds all in the past month in addition to increasing my exercising. Am I making myself anxious for nothing? Is it normal to miss a period with all of these factors? Any thoughts or recommendations to ease my anxiety would be appreciated!
