Can a pregnancy blood test give a false negative?

I have just recently switched birth control pills (about 2months ago)and last month I had my regular period.  I have not missed a period yet, but for almost three weeks I have been nausea off and on all day long with indegestion and have been extemely tired.  I have taken three home pregnancy test and one out of the three was positive.  That was last Wed. night, Thurs. I went to the doctor and he did a blood test that came back negative.  The thing is I have never reacted to BCP this way before.  Could I be pregnant and getting a false negative from the doctor?  If anyone has any advice or suggestion I would sure apprecitate it.

Thank you!

I went to the hospital sunday. They did a blood test and it came back saying I was pregnant. The next day I went to the clinic for prenatals. They did a blood test and sent it off. The results for that one was negative. How is that possible?

Hi, Which blogs and stories do you recommend reading regarding negative blood tests and finding out later they are pregnant? I'm feeling VERY pregnant but my blood test came back negative yesterday... I can't understand what else my symptoms would be attributed to if I'm not pregnant... Help! Any blogs or stories would be helpful in understanding what's going on! Thanks a lot.

BLOOD PREGNANCY TESTS CAN BE WRONG!!  This is known as a "Cryptic Pregnancy".  Women who experience this NEVER get a positive test. I have created a support group for this on Facebook called "Cryptic Pregnancy Support Group".

The Jen989, sounds like we got the same problem. I too have the mirina IUD and I'm positive I'm about 4 months pregnant. I've done 4 home tests two of which were positive (first two) and two negative (last two), and also a blood test at the doc and came back negative. I have gained weigh most in my stomach which is really odd because thats the part of me that was always the skinny/flat part of me. I'm never been an eater but now everything taste good. I feel movement in my stomach daily, plus I have many other symptoms of pregnancy. This would be my first baby, and though I feel totally really, I'm scear of what the IUD might do the the baby if there is one growing inside me. I have a doc appoiment for this week to get my IUD removed so all I can do now is wait:(

This exact same thing happened to me! I hadn't missed a period in a very lobg time, but I missed all of Nov. and still had not gotten one. Went to tge dr and she gave me a preg test that was neg. She didn't give me a blood test which I thought was very odd, but I was so disappointed from the - urine test that it didn't cross my mind to ask for one. I'm going to call and schedule a blood test asap. I have been EXTREMELY fatigued to the point where all I want to dois sleep, and that's so unlike me.

Thank you for sharing your story.  I have pcod too! I went to the dr last week because my period didn't come the whole month of November which is the first time that has ever happened for the past couple of years. I am incredibly tired every day to the point where it seems I sleep or very sleepy the majority of the day. I've never felt this exhausted in my life,  and there's no other reason why I should feel this tired. Anyway, my pregnancy test was negative, and for some odd reason she didn't offer a bloodtest, but I'm going to demand to have one done asap! I'm kind of afraid because the dr said if my cycle doesn't start by the middle of this month, she's going to give me meds to make me ovulate, but I don't want to start anything without knowing completely sure I'm not preggo.

I had a negative blood pregnancy test in hospital and 3 negative hpt's. I was 3 1/2 weeks late on my period and very symptomatic! I just KNEW I was pregnant.. even though all the tests came out negative! As a woman, you know your body! I waited a week and a half and then re-tested! This time I received a very faint positive result on a hpt. I had taken it at night, so I re-tested in the morning with the first morning urine. Very dark positive! Some women's bodies just don't build the hcg hormone as quickly as others and require more time to produce enough of it to test positive for pregnancy! Good luck all!

Hi can someone please help me. I just took my first blood pregnancy test today and it said I was off by 2 and I don't know what that means. I have taken multiple HPTs also a few clinic tests and the very first one came out positive but now everyone is coming out negative that I take but I know I'm pregnant because my body tells me that I am and I even have a bump. I've tried getting a doctors appointment but they all say I'm not pregnant due to the urine tests coming out negative. My the way my stomach is protruding I should be almost their. Please help me I'm really confused.

Hi. Just wondering if your period came? A lot of times if you exercise a lot or jog/run that can delay your period. I know several women this happened including myself. One friend couldn't get pregnant and I knew she ran 5 to 10 miles a day. I told her to start walking and in a month or so she got pregnant. So if you want to get pregnant stop running, if not keep it up. Anyway, don't know if thats helpful.

Hi there, i am very depro at this stage.

I have been 18 days late (are never ever late), done 2 HPT's and both negative, went for a blood test at the doctor and also came back negative. I have experienced little bit of spotting a week ago and feel every now and then nauscious and get headaches more often.

Please can someone help.
Is it possible that the blood test can be faulty? I was really excited about this because its my first time and I have been trying for the last 3 years now and after the negative blood test, it made me feel down in the dumps again.

Hi. Im also freaking out! We have been trying for 4 years; had 2 mc - both around 6 weeks I had to have D&C for recent one. Now I totally feel pregnant. I think conception was 22.02.13 when I was fertile, then husband been away since then. As I have had normal periods since (although the last one was really bad cramping and only lasted 3 days) I was waiting till he gets home in 3 days to try again. I really want children, but I dont think my body is tricking me into thinking Im pregnant, as Ive been waiting for hubby to come home. Now I have major pregnancy symptoms. Extreme nausea, fatigue, recently started being sick if I eat anything other than chicken soup and today my bbs are sore. 4 hpt negative, dr took full bloods for thyroid etc and all negative and she did preg test which was negative. Dr no idea whats wrong... What do I do now? Its driving me crazy. Should I get u/s just incase?
