Some pregnancy symptoms include:

      • nausa
      • missing your monthly periods
      • fatique
      • food cravings
      • back pains
      • headaches
      • swollen breasts

      You could be experiencing these symptoms for other reasons than pregnancy though (such as stress, a hormonal imbalance, or a stomach disorder.)
      You could take a Home Pregnancy Test, but then run the risk of getting a false reading. It is best to check with your family doctor. Try not to panic; you may not be pregnant.

      Good luck.
