DH & I have been TTC for about 18 months, with no success as yet. AF non existent, tried Clomid for 2 cycles, no ovulation. Now on Puregon injections. Started on 50 IU each day, now after injecting every day for a month up to 83 IU. US every week. Just wondering if anyone else has been thru this - trying to figure out at what dosage Puregon will make you ovulate?
