If you've missed your period, and feel basically the same but a little worse as pms (nausea, Brest tenderness, etc..) and/or heightened sense of a smell and craving. You know your own body better than anyone else. If you feel off... Pick up a test. Be aware there are false positives and the OTC tests sometimes show negative when in fact you are pregnant. The BEST advise is to go see a doctor. Call your cal planned parenthood or you state service building most states offer FREE or low cost healthcare to pregnant women that need it. Good luck and best wishes.
