If you took all four tests too soon, they could have been unable to detect anything. If you've missed more than one period, you may wish to consult with a doctor.
7 days after implantation it is possible to show positive on a pregnancy test. If it's negative, wait a few days and test again.
No long duistance answer - see a doctor.
Please see a doctor.
Very, very unlikely if you're doing the tests right.
Yes, absolutely. Every woman produces different amounts of hcg, which is the hormone that the pregnancy test detects. It can take some women a week after implantation (or longer) to produce a detectable amount of hcg for a blood test.
i started what seemed to be my period 4 days early it was very light and only lasted 2 days. implantation or just an abnormal period?it was dark red just like a period but it was just a lot shorter, normally i have a 4 day cycle and it was lighter. i took a test but it was negative, possibly i took it too early?
Definitely! If it is too soon you will get a false negative even if you really are pregnant. I would wait about a week and then take another one, it is going to be more accurate the longer you can wait!
My negative critics usually block my answers, so yes, I get very sensitive about them.
If it's not a "regular" period, yes. It could be implantation bleeding: http://www.epigee.org/guide/lateperiod.html http://www.ynhh.org/healthlink/womens/womens_4_04.html
See your Doctor for a Quantitative beta HCG pregnancy blood test. You will need to ask specifically for this blood test.
I think a home pregnancy test taken during implantation bleeding would be a little too early to take. wait another day or two and then take it. But it might be OK to take it then. Depends on the test and the woman's hormones. My personal experience is that you can take a HPT during the first implantation bleeding and see a positive result that has inevitably turned out to be accurate. However, Just because it is negative doesn't mean that the test is acurate because all woman are different and sometime a woman's hormone levels take longer to kick in.
I am waiting to go to the doctor to confirm how far along I am. I know I'm pregnant but I did a test over a month ago and it was negative, plus I had what seemed like a period but apparently I am at least 6 weeks. I believe that you can get pregnant and still have an actual period for 1 or 2 months. I have not gotten a period since. so my advice is to wait, and take tests. sometimes tests won't show a positive for about 5 weeks.
