At least 20 eggs at 1cm or more and I've only been on the Follistim for seven days. I will have to go tomorrow morning for yet another "John Holmes" ultrasound (Oh, joy). My MD is concerned that I might be overstimulated & that could lead to possibly serious side effects...This is from the American Society for Reproductive Medicine's fact sheet on the side effects on Gonadotropins

{hormone that stimulates the growth and activity of the gonads, especially any of several pituitary hormones that stimulate the function of the ovaries and testes.}

Ovarian Hyperstimulation Syndrome (OHSS)... Occurring in 1 to 5 percent of cycles, the chance of OHSS is increased in women with polycystic ovarian syndrome and in conception cycles. When severe, it can result in blood clots, kidney damage, ovarian torsion (twisting) and chest and abdominal fluid collection. In severe cases, hospitalization is required for monitoring but the condition is transient, lasting only a week or so. Occasionally, drawing fluid out of the chest or abdominal cavity helps. The best prevention is to not give hCG to indue ovulation at the end of an overly vigorous stimulation cycle.
