ME, TOO! I had spotting for three days. LIGHT. And that is what did it for me. The blood work was the determining factor. Every person's body is different.
On a side note? I am on my 5th day of 10 units of Lupron with my gonal-f shot (the stim shot). My gonal-f was 300 units. By day two, my blood work and sonogram indicated I needed half a dose. So it's 150 units.
It's bizarre. With a smaller dosage I am still groggy at night. It's not too awful. It's an adventure.
So, don't worry about your period. Every single woman is different and your blood work and sonogram will dictate the information.
