Yes, if you didn't take the test at the right time or followed the directions correctly the test could come up negative. It's most effective to take a pregnancy test the day before your missed period. Wait a week and then take the test again. Or go to the doctor for the most accurate answer.
noo
Having two tests after each other fail would be improbable but not impossible. Most löikely you're not pregnant.
yes.
Tests do fail occasionally, but it'd be very unusual for several to fail. Only drinking water reallu doesn't affect the tests much either way. If they say no the very good odds are on that you aren't pregnant.
Yes. All birth control methods can fail. If you feel that you could be pregnant you should take a home pregnancy test and/or see a Dr.
Condoms are not 100% reliable so there is still a chance of pregnancy occurring. If you think you may be pregnant you should take a home pregnancy test and/or see a Dr.
Don't risk it, see a doctor.. Pregnancy tests aren't always exact.
A home pregnancy test is most likely to be accurate if it is positive meaning if you had a negative test you should be monitoring if you could be pregnant. You could have taken the home test too early to detect pregnancy. The best thing to do is to go to the doctor and get a test done there to rule out pregnancy.
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.
Constipation is just a symptom of pregnancy...not a sign of pregnancy. Many women experience bouts of constipation during pregnancy, but if you do not have constipation then count it as a blessing. If you take a home pregnancy test and your doctor confirms your pregnancy then you are pregnant with or without constipation. Good luck! mom to three children and pregnant with her fourth!
Oh yes! Tests are only about 85% accurate. And some conditions might cause the test to fail more often.
You are pregnant
It is NOT likely. To confirm, I reccommend taking an at-home pregnancy test.
