Still nothing...

Ashley
I need answers! I'm 13 days late still with 3 BFN. I took my last test on Monday before my Dr appt (which went terrible) she didn't give me any answers and just said to test again this weekend. If I don't get my period by this weekend then she can give me medicine to kick start my period. I'm just confused because I've never been late and now I'm 13 days late....shouldn't I be pregnant? Shouldn't she of done blood work or at least try to figure out why I'm late. On top of it I've been sick the past few days, extremely nausea and pain in my stomach. Hot flashes and headaches. Has anyone experienced this or know what I should do?
