I'm 12 days late for my Menstrual Cycle...but...?

The easiest solution is the most difficult...you have to stop worrying about it. This has happened to me before and I was almost a month late because I couldn't stop worrying about the fact that I might be pregnant. When you catch yourself going over "What will I do if I'm actually pregnant?!" in your head, remind yourself that you're not and everything is going to be okay. If you can relax, it will come faster and you'll feel much better :) Good luck!
