What do you think?

Can you get positive on a cheap pregnancy test, and then get negative on first response? What could that mean if you do?

Right, that is what I meant by maybe you had a chemical pregnancy.  That is a pregnancy that begins and then ends rather quickly, a miscarriage doesn't even happen in an obvious way, but if you are testing, you'll come up with a positive and it will be followed rather quickly by a negative.  The sequence of events is that an embryo begins, and the cells start to divide, and it implants, with a beginning placenta producing hCG, but then it stops in a day or two and fades.  So a test when the placenta is producing hCG will give a positive, and a test after it fades will give a negative, all in the first couple of weeks after conception.

Hi Mandy. I have been using CVS and Rite-Aid brand tests and getting really, really faint lines. I don't know if a name brand is any better than a cheapie. I would definitely call your doctor and go in for a blood test, just to be sure.

Good luck hon!

The thing is that the positives were ahead of the negatives.

Some of the cheap ones are surprisingly sensitive.  It might be that you have suffered a chemical pregnancy, or it might be that your urine was less dilute with the subsequent test.

Cheap ones work just fine. I used 4 and all said positive and I'm 6 weeks. Take a few more and if still inconsistent then get your blood checked at doctor to make sure.
