Missed period for 8 weeks blood test negative why?

It's possible. Depends on whether or not you took the tests too soon. You should wait a couple of weeks past your missed period before testing.

no it can't tell you if you missed your period for 8 weeks

Home pregnancy tests are designed to be used AFTER your missed period. Using it 2 weeks before a missed period could skew the results.

I'm 2 weeks late and I have taken 3 pregnancy tests and a blood test all came back negative. I have all the symptoms missed period, sore breats, and morning sickness. Could a blood pregnancy test be wrong? or could I have had a miscarriege?

Maybe its cause your period is changing cycles. it might come later like it usually does

As the blood test is negative it is unlikely you are pregnant. However if you 'feel' pregnant and had sex at your fertile time it might be a good idea to take a home pregnancy test two weeks after your missed period.

its possible, wait a couple weeks and take another

Wait a little longer atleast until like 2 weeks or so after your missed period and take another test then

It is possible you are pregnant though I would have expected an HPT to be positive. I suggest you go to the doctor.

you will have a missed period.

Unlikely, but it might have just been too early to take a test. If your period still hasn't arrived in 2 weeks, take another one

i had artificial insimination two weeks i did a blood test and its negative should i re test again my blood on my third week i have no period at all

My period is also late, 3 1/2 weeks. I've taken 3 hpt, all negative. I have no symptoms of pregnancy at all. My periods are usually very regular, and I always know when it is going to come. What should I do?

40 weeks or nine months.

well, think of when she missed her first period....then count back 2 weeks and there you go. this is the case since ovulation typically occurs 12-16 days after your last cycle. and then about 2 weeks after that you have your period. so just take when you missed your period and count two weeks before whatever the first day your missed period could have started....

I get nauseous when you don't miss your period.

red blood I've got told that means a miscarriage is on it way if it were spotting no flow then that's a pregnancy sign

If you haven't gotten your period in a week retake the test or go see your doctor. They can draw blood to check to see if you are pregnant.

from the day after you realise its missed, to the next 3 weeks in the cycle...

You should take a pregnancy test shortly after your missed period. That is when a home pregnancy test is most effective. Although I have heard you can do a blood test at the doctor as soon as 2 weeks before your missed period.

No. Typically it takes somewhere between 3 and 5 weeks after a missed period for it to show up on an ultrasound.

2 weeks or after the missed period.

2 weeks after your 1st missed period

It sounds as though you might be. Sometimes the hormone level does not get high enough to register until a few days after a missed period. It took two weeks for me. Happily I had a positive test on my birthday. Answer so you didnt get a positive until 2 weeks past your missed period? and did you test in between? i am testin every 3 or 4 days

Your first sign of pregnancy is typically your missed period. Symotoms, such as breast changes, begin to occur within the week of your missed period or it could eve be 1-2 weeks after the week of your missed period.
