Hiya MissyMooMoo,

In my case i was given pregnyl to make me ovulate. I usually ovulate on my own but since the fert clinic is closed over xmas i needed to ovulate before the 21st dec to get a FET in before xmas. i was running out of time so they gave me a pregnyl injection and i ovulated 36 hours later. the only problem is that it is made from the HcG hormone which means that POAS may give me a false positive.

Hope that answers your question...
