I was due for my period on the 6th and still nothing... I haven't even had signs of getting my period... I took a test a few days ago and it was negative, I have heartburn all day and night but I'm not eating anything spicy... I'm craving more salty foods rather than sweet like when I'm near my period. Could I be Pregnant?

It's possible... see what happens in another week. Your period may just show up later this cycle. Try another test if still no period. If negative, wait until next month and test again if necessary.
If you feel you start to have other possible symptoms before the next period, you could test sooner or see your doctor.

Of course you could be pregnant. If you had sex, pregnancy is always a possibility.

Remember that PMS and pregnancy symptoms are very similar.

Also remember that at one time or another all women are late and it's not necessarily because of pregnancy. Many things can cause a late period, for example, change in diet, illness, medication, weight loss, weight gain, and so much more.

Wait another week. If you still haven't gotten your period try another hpt, use first morning urine as it's more accurate, or go for a blood test.

Good luck.

Yes you could be pregnant... try testing again if you are 3 days late then you should be able to get a positive this time.. you tested a few days ago and it may have been too early... try first morning urine and another HPT and if still no period consult your OB if you are still concerned
