I am 25 years old. I got my period last month on the 20th, it is the 29th and I still haven't gotten my period. I been so stressed out that I'm not eating well or been sleeping much, could that be a reason ? There's also the possibility that I could be pregnant since I been sexually active with my partner without using any protection.. Please tell me if you know anything about this because I really have no idea since I don't have any kids, anything will help, thank you in advance..

For some women, stress can effect their periods, but of course pregnancy will be another possibility. If your period has not shown when you expected it to, try a pregnancy test. Be sure to follow the directions carefully.

If negative, see what happens when you expect your next period. If you feel that you start to show other possible signs of pregnancy, you could always test again in a couple of weeks time.
