Tests done at this stage are usually quite accurate. Unless you've used a cheap brand, I'd retest in a few days and see a doctor if the result is still negative but the periods continue to be different to usual or there are other signs you are worried about.
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.
. . . means that you arent pregnant.
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 are pregnant
Yes
Unlikely - the bleeding probably was your period
Having your period means you aren't 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.
Your period shouldn't affect the test! There is really no point in doing a pregnancy test during a period. Usually, if you are having a period you are not pregnant. A pregnancy test senses the BHCG hormone so your period should not affect it.
Most likely your period. You're probs not pregnant.
If you are on your period and u take a pregnancy test and its negative maybe you tested too early, your not pregnant or your eggs aren't coming together fast enough to tell if your pregnant or not .
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.
