Plan B Nightmare / Am I selfish?

So back in early December I had a one night stand that resulted in me needing to take a plan b, well after a month and half of no period it finally came and I found myself leaping for joy. Now mind you I had taken several pregnancy test, even a blood one that told me not to worry and just relax but of course being 20 and almost done with school I couldn’t just relax.

Though yesterday as I finally got my visit from Aunt Flo I felt a little selfish for being so happy since there are countless of women who cannot conceive and I thought of all the things I would do if all those test were wrong but I wonder if I’m selfish for being over joyed about my happy ending?
