htere is a possibility, but it could be just that your period is coming later than usual this month. usually females cycles don't become consistent until at least late teens to twnetys depending on how long you have had it for, i wouldn't worry about only four days. but if you don't get it for a while longer, then you should see a doctor or someone at a pregnancy care centre to get an accurate result. good luck.
Mine once came a week and a half late. These things are very unpredictable. Don't worry, as long as the test says negative, you're probably okay.
I don't know for sure but my period was 1.5 months late once and i did a pregnancy test which was negative. The next day i got my period and I'm not pregnant so I think it's just a late period. Your mind probably gets worked up about not getting it and therefore prevents it but as soon as you confirm your not pregnant you relax and therefore the cycle starts.
No you can't be pregnant and still have your period. You can have a light bleed but not a period. As for the whole negative test thing, it could be a false negative.
I hate to state the obvious, but if you are pregnant you would get a positive, if you are not then it would be a negative.
You can get pregnant a week before your period, the week of your period, and the week after your period, and some pregnancy tests are faulty.
. . . means that you arent 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.
Unlikely - the bleeding probably was your period
Having your period means you aren't pregnant
Visit you doctor.
You are pregnant
If you have had a negative blood test, it is very unlikely that you are pregnant
Pregnancy tests are not 100% accurate, but being that it was negative and you got your period, I'd say you are definitely not pregnant.
If you're on the birth control pill and had a negative pregnancy test, it is not likely you are pregnant.
