<s>[INST] Dear sir/ madam, we were monitoring the follicle growth using ultrasound. on 13th day the follicle size was above 18 mm, but on 14th day the follicle was missing and free fluid was there. We have done an IUI at that point of time. We have undertaken HSG test on 13th day and the result is that everything is normal. We have undergone IUI in previous cycle also but at that time no free fluif was present. What are the chances for a successful pregnancy this time [/INST] HelloThanks for writing to HCMOvulation has occurred this time.This is indicated by missing follicle and free fluid in POD.There are chances of pregnancy this time.You should go for IUI because chances of fertilization is maximum with 24-48 hours of ovulation.You should consult your gynecologist.Hope i have answered your query.Take CareDr.Indu Bhushan </s>
