most definitely yes. You can be pregnant and still have a negative test. If you do get a positive test though it is rarely wrong and means you are pregnant.
no.
Yes you can
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.
you could be pregnant
Stress, change of life styles, it could be a many of things.
all i am going to say is go to the hospital please
if you period hasn't come, theres a chance. probably worth getting a test
If you have had a negative blood test, it is very unlikely that you are pregnant
well i don't think it could be possible
No. If you got a period after July, then you did not get pregnant in July.
yes you are pregnant
no age limmit, you can even have it b4 your period. some girls have even had it at the age of 12!!! I am 13 and a half and I still havent had my period, I could still get pregnant.
