So I'm an 18 year old and my last menstrual cycle was January 3 its now March 16 I still haven't had my period I've tooken 3 home pregnancy tests at different times, they've all come at negative. I took another at the clinic,another negative . I live with my fiancee and we are both confused if I'm pregnant or not. I feel a lot of symptoms, I just wanna know how else I can find out so I can start prenatal care. Thanks for any help
