It can happen let me explain without to much to read... There are two types of blood test that a doctor will do.. One is called the quality blood test (and to be honest you might as will buy the over the counter hpt).. the second one is Beta which counts the hcg in your system to determine if you are below 5 or 5 and higher... So make sure you question your doctor which one he is going to use before you spend 50 buck for an 5 dollar deal at a drug store. Good luck to you all
I am right there with you. When my husband and i first thought that i was pregnant i took the home test. Postive! great! we went to the hospital and did the blood test and it was negative. i went home upset but not convinced. i took another home test and still positive. i called my doctor then and asked why my home test were positive but the blood work was negative. She told me to come back in and they would do an ultra sound to be sure. YEP i was pregnant, 6 weeks! they were never able to tell me why my blood work comes back negative. but i now have a healthly lil boy born right on time. ONLY because i didnt believe them from the beginning. YOU KNOW YOUR BODY better than ANYONE else if you think something is different you're most likely right. Dont give up!
I am in the same boat, i took a blood test and it was negative, took a hpt and its positive have all the signs of pregnant, sore breast, tired, cranky and feel pregnant. I don't feel like I have PMS I know the difference, my period is not due till Friday so I will wait it out and see, I know my body and I know this is not PMS.
