Clomid and four follicles?

Are they going to do another U/S on day 13 or 14? All of those follicles may not continue to grow- they are all pretty close to 16, but isn't it 18 or so before they are sure that they will ovulate? I also think it depends on your age. I used Clomid in my 20's and only ever got 2 follicles at a time. My RE was hesitant to put me on anything stronger because of the risk for more follicles, however, he told me that if I was 35 or over, he would be more willing to let me produce more because they wouldn't all be of great quality. If it was me in your situation I would go for it! We once did a frozen embryo in vitro transfer with 4 beautiful embryos and got no babies- the chance of 4 unfertilized eggs turning into quadruplets is highly unlikely- twins maybe. Do whatever your heart tells you to do!
