I am 19 have a five month old who is the best thing ever but I have been having unprotected intercourse sense he was two week and two days old I have been regular for four months and I am two weeks late and I took 3 test and they came back invalid I have all the systems that I had when I was pregnant with my son has this happened to anyone else

When you say the test was invalid? Did you not get any results in the test window? Have you been using first morning urine? If you answered yes then I would suggest you make a dr appt, and have them take a blood test, that will be the best way if your test results are invalid.

A quantitative human chorionic gonadotropin (HCG) test measures the specific level of HCG in the blood and they would be able to tell this as early as 10 days into your pregnancy...

Did you get a very faint line? A negative line?

OK dd not get a line in the result wendo and it is supposed to make a + sign y are and a - sign if yor not and I ddnt get eather

Okay invalid test can be either Too much or too little urine on absorbent tip may cause an invalid result, or a defective test, were the test all from the same packaging?

Anyway every few days your HCG levels double, so if you can't wait to go to the doctor wait a few more days until your HCG levels are detecable use first morning urine as it is the most concentrated. Use a different test brand perhaps try the digital one, it works fast and very accurate. It will simply say pregnant or not pregnant... just wait a few more days and retest if you still get an invalid or a negative go to the doctor to have blood drawn.
