It depends how fast you metabolize it. Best to you.

Probably. It depends on the dosage of the shot and your metabolism. Hcg generally has a half-life of 27 hours, meaning every 27 hours the amount in your system is reduced by half (the time can vary a little bit depending upon your metabolism). For Ovidrel 260mcg (which is approximately 6,700IU), it takes about 11.25 days for hcg levels to drop below the threshhold of very sensitive hpts.
