One week isn't long enough for any pregnancy test to detect the hormone levels associated with pregnancy. You will need to wait at least 4 or 5 more weeks to get an accurate positive test result. Take note of how long your spotting lasts and tell the doctor when you go to the blood test, as that is the most accurate test you can get.
Periods/spotting can be brown, dark or of red color. Brown/dark color of the periods/spotting is due to delay in periods. Old blood is usually of brown or dark color. Delay in periods can be due to pregnancy, hormonal imbalance, stress, and polycystic ovarian disease. If your spotting has lasted for just one day then there is chance of pregnancy. Reliability of home Pregnancy test is 75-96%. In my opinion, you should get pregnancy test in blood if full flow of periods has not started yet.
Was it light and brown or pink? If so then you could.
Probably not. If your expected period date is already 1 week late, you should be able to detect a pregnancy on a home pregnancy test.
My period is 1 week late, took pregnancy test negative, have spotting for 3 days then 4th bleeding can I be pregnant?
It's lighter and brown and pink and just my under wear is dirty the first Day it was just a teeny bit on my under wear and yesterday the under wear got a little dirtier and now it's the same I don't feel like it's my period no bloating or cramps what could it be?
If you start your period when you are pregnant you can have your baby with more blood than usual.
Just like if you want to have sex and your pregnant nothing will happen to the baby.
