if you are worried you could always see your doctor for a urine or blood pregnancy test that would tell you for absolute certain. however it is not always a concern if you miss a single period. often excessive exercising stress anxiety can cause a period to be missed. if you miss your next one i would consider seeing my general practitioner or family doctor just to be sure there are no underlying issues.
missed period but negative test for pregnancy am i pregnant or is something wrong with me? . i was suppose to have my period on the first of january i am never more than a day late and i keep track of my period and ovulation schedule via a calender. i have been nausea at work. my skin has been really sensitive to touch. i have been so tired as well. i'm not under any stress but when i took the test on the 3rd it came up negative. i used the first response pregnancy test. my husband and i had sex frequently through my ovulation window as well.
