Every woman's metabolism is different, but as a general rule of thumb, you should allow 1 day for every 1,000 units of hCG you injected. The standard hCG dose is 10,000 units; thus, 10 days after the shot, the synthetic hCG should be gone and you should be able to test for pregnancy without detecting the shot. However, you should ask your doctor what the recommended protocol for your dosage is.
Some women choose to test daily to monitor the essence of the hCG in their bodies; once the synthetic hCG is gone, the tests become negative. If the hCG "comes back" and the HPT's turn positive again, it's likely due to a pregnancy and not the leftover hormone shot.
I would reference the site but I don't remember which of the 4,000 sites I looked at it was on... sorry!
Anyhow, we are just hanging in there to see how this goes.
I will say, however, the only time I have ever seen any sort of positive was the first time we did it, which is when I had what I believe to be an amazingly early miscarriage. I stupidly did not really acknowledge it at the time and made no effort to slow my life down whatsoever afterwards, and ended up giving myself shingles.
NOW COULD SOMEBODY TELL ME WHAT A BETA IS???
I did go in Friday to have my progesterone checked and we will find out the results first thing tomorrow (Monday) morning. Depending on the results, I may need to go in for a dose of extra progesterone, so I can try to hold on to these hopefully fertilized eggs.
