I took 125 mg (half of a 250 mg shot) 3 days ago and I want to know if it’s out so that I can do a home pregnancy test. I am 6 days post transfer.

I found this on the Internet:

I found this by googling "ovidrel half-life" The Half life of a drug is how long it works/ stays in system. The half life of a drug has a calculation that is based on a "healthy system". If one has a liver or kidney problem, for example, the half life can be extended.

I called my pharmacy and asked how long ovidrel 250 mcg stays in your system, and here is what he said:

It has the half life of 29.2 hours, so that means this:

29.5 hours from the injection it is 50% out of the body, then every 29.5 hours, that amount is cut in half, he gave me all the figures:

-50% out

-75% out

-87.5% out

-93.75% out which he said is considered completely out.

So here is what I calculated for myself last cycle:

3/26 - 7:30 am injection

3/27 - 1:30 pm 50% out, 50% left

3/28 - 7:30 pm 75% out, 25% left

3/30 - 1:30 am 87.5% out, 12.5% left

3/31 - 7:30 am 93.75% out and 6.25% left

You keep dividing the number by 2 (6.25 / 2 = 3.125%)

and so on...

Does anyone have any experience? Wondering if I should just divide that timing by 2 ie slots of 14.75 hours as I took half a shot.
