quantative blood pregnancy test

I've been lactating and wasn't sure if I was pregnant.  My doctor did a blood test to see if I was and also did a hormone test to see why I was lactating if by chance I wasn't pregnant.  Also at that visit she put me on hctz because I've been retaining water and wanted me to take it every other day.  She called yesterday morning to let me know that I am in fact pregnant, this was after I had just taken the hctz.  She of course toldme not to take it anymore..
  I had already had a quantative blood test scheduled with my other doctor because I suspected pregnancy and wanted to know how far along I was.  Later yesterday evening that office called to let me know that I am not pregnant.  Could it have been negative because of the hctz in my system?  I'm confused.

Hi!
If you had a negative blood test that should be pretty definitive.  HCTZ will NOT affect a blood test.  It COULD affect a urine test by diluting the urine though.
If you were my patient, I would repeat a blood test in 48 hours to see what exactly is going on.  In the meantime, don't  take the HCTZ.  It won't hurt the baby, but is not good for you or the baby either.
Good luck!

Thank you so much for the helpful information.  I'm scheduled to go see my gynecologist May 3rd and if I'm not pregnant I guess the next step is to see why I would be lactating.
Thanks again!
