I was in tamoxifen ( 2 to 6 days )  and humog injection 75Iu ( 3,5,7 th day ). on day 9th the follcile size is 15 and 11 , so doctor asked me to come on day 12 . Day 12 ( one is ruptured ET 7.5mm without any hcg shot and one more follcile size is 19mm which is not ruptured yet  ) Doc asked me to come on day 14 to review if my another follcile is ruptured or not . Is there a chance for follciles to rupture at different time intervals? And should I consider taking hcg for another follcile to rupture?
