I just started the IVF process and I am on my 3rd day of the lupron injections, 5 units. I started having hot flashes, and sweats lasting the better part of today, I also am experiencing a mild headache. I thought i would get online to see if this was typical for the medicine. I am also taking birth control pill wich will stop tommorow. I haven't taken BCP's in over 16 years and only for a few months. The BCP's did have me nauseous, and a little moody but i have seen a marked difference in the taking of the lupron in just three days. Only 5 units I am thinking whoa! I can just immagine what will happen over the next few weeks of this.
