Been tired (out of the normal for me to take naps), been moody (along the lines of crying) , also my hips hurt all the time. could i be pregnant?

Not primary signs: Those are not the primary signs of being pregnant. Missing a period is. If you had unprotected sex , especially during your most fertile time, and your period is overdue - yes, you could be pregnant. The energy and emotional issues and pain deserve your attention, but would not be related to such an early stage of pregnancy in all likelihood. Take a test if you are late and take care in the future.
