Hi..you haven t mentioned anything about your menses..if you have missed them by any chance or there is some alteration from the normal pattern, immediately perform a urine pregnancy test by self at home..dmpa 2 wks after the unsafe sex episode might not protect you because fertilization and implantation would have already occurred..plus you are also having symptoms, so an urgent upt is advised.. Your boyfriend having craving symptoms and excessive sleep etc etc are not at all related to your pregnancy..(that s a bit weird)..so he should get a medical evaluation separately..
