confused...

ok, so when i first got pregnant i found out from a home test and i week or so later i went to the doctors and they gave me a blod test to confirm... i was about 4 weeks according to the test which meant that i was about three weeks when i took the home test... since then i have joined the military and am pregnant again... when i first thougt i was pregnant i wen to the doctors and again took another blood test and it came back totally NEGATIVE... but apparently i was cuz two weeks later i went back and was a little more then five weeks... i dont uinderstand how they couldn't tell at about 3 1/2 weeks that i was pregnant but two years before that another place could... How is that? and finally why Everytime i go to the doctors and get an ultrasound, it calculates differntly of how far i am... im supose to be 24wks 2day and it'll say 25wks 4days or something like that it never stays the same!

ultrasounds are never 100%.. i just had one lst week and i was supposed to be 37 weeks but my baby was measuring 35-36 weeks. the doctor said it was normal. as for the positive/negative results i have no idea! i wouldnt worry about it though as long as everything looks good now. good luck!

because you may have had a qualative blood test - this has a detection level of 25, if you are under 25 they say not pregnant. However your levels may have just been slghtly lower than that, thus a false negative.


U/S upto 7 weeks accuracy is +/- 3 days. After(i think its 12weeks)the u/s scans only have an accuracy of +/- 10 days. Its the same way that they can be upto 1lb wrong in estimating the babys weight.

This is off your topic but where at are you? We are AE, my husband was AP and he was in Korea.
