Yes, you have to give the hormones time to build up
Yes it can. My advice to you is if you feel that you really are pregnant, buy several test, and if they are all negative and you STILL think you're are pregnant, go to the Dr. and get him to test you.

What if you take three blood tests and two came out positive and one negative?

I would head back to the doctor for another blood test. You may have taken the negative tests too early in your cycle for it to pick up enough of the hcg hormone. Good luck to you Nancy http://thefertilityshop.com It depends on the order of the tests. If the last one was negative you probably are not pregnant. If you had bleeding and/or cramping, it is possible you had a misscarriage, the HCG level drops and could have been positive initially then dropped below the detectable level. Usually if misscarriage is suspected they do a quatitative HCG level and follow th level to see if it is going up or down.
