Not all home pregnancy tests are 100% accurate. They CAN give false negatives AND false positives. Wait a day or so before taking another test--your period just may be irregular due to health or stress reasons. If you are on Birth Control, the hormones may be causing irregularity. Whether or not you take contraceptives, consult your general practitioner/gynecologist for a pregnancy test.
If you have a negative pregnancy test, you are probably not pregnant. What makes you think it's not your period? (ie. did you have a pos pregnancy test earlier?)
No. Spotting can occur during pregnancy.
The only way to know is by taking a pregnancy test.
Sometimes women have implantation spotting that they confuse with their period. You should take a pregnancy test to see if you are pregnant.
Spotting is very common during the course of pregnancy and the combined symptoms of spotting then a missed period certainly could indicate pregnancy. However it is very common for women who are not pregnant to have a missed period or spotting. I suggest a pregnancy test which are readily available at almost any store and to consult your doctor.
You could be pregnant. Take a pregnancy test
Take a pregnancy test
Spotting usually happens when a woman was pregnant, and lost the baby/had a miscarriage early in the pregnancy.
You are unlikely to be pregnant on the implant. Signs of pregnancy are absent bleeding and positive pregnancy test.
Not all women spot. Some women will have spotting with 1 pregnancy and none with the next. If you think you are pregnant, see your doctor or get a test.
Only about 30% of women have implantation spotting. It is not necessary for a healthy normal pregnancy.
Spotting can possibly be a symptom of pregnancy.
