Many of the symptoms of pregnancy are associated with pms as well. Breast tenderness, cramping, etc. Nausea can be brought on by stress and a host of other things as well as pregnancy and pms.
The body also doesn't adhere to a calendar and many things can effect the timing of your period; sickness, stress, exercise, change in diet or sleep habits, weight loss or gain, a number of things. It's completely possible to miss a month's period entirely.
If the npt says no, I would trust it but probably take another test made by a different manufacturer if I didn't feel comfortable and see what that result was. If it confirmed the first test and you are sure you took both properly (didn't contaminate the stick by laying it down, etc) then I'd chalk it up to a change in habits and wait a month.
If you want to be 100% positive consult your doctor.
You could by a small chance, but, you might also imagine the symptoms (phantom pregnancy). Or your pregnancy is too small at the moment. Try testing again in a week or two (when your period hasn't started). If still negative and you got the symptoms and no period then go see a doctor.
your not suppose to get your period when your on that
You could be pregnant, but if I were you, I'd go straight to my doctor.
when in doubt, assume you are pregnant. then take a urine pregnancy test, and if that is negative. then you can also check by getting a blood pregnancy test.
If you are on/had your period your probably not pregnant, but do a pregnancy test to be sure.
no because your period controls your pregnancy.
Not necessarily. Many women experience symptoms similar to menstrual symptoms around the time of their expected period when they are actually pregnant. If you think that you might be pregnant, and you are a day late on your period, you might take a home pregnancy test to find out.
Yes you can be pregnant.
The negative pregnancy test is the defining answer, regarding pregnancy - once your period is a week or so late - if you are pregnant, the hCG will be high enough to be detected.
Yes you can
. . . means that you arent pregnant.
Considering you ovulate about two weeks after your period, if your last period was in fact a period there is only a microscopic chance that you would even BE pregnant, much less be experiencing symptoms.
