<s>[INST] Hi my follicle size is 18 mm on 8th day  and endometrium is 6mm itself so pls suggest should we have intercourse today......and my doct says its not a gud cycle..and follicle grow is fast.and sugests to go for iui if endometrium improves....pls sugest [/INST] Yes in your report follicle is with good size, but the problem is with endometrium size. You need at least 12 to 14 mm, so it's not possible to implant in this endometrium size. If this type of patients come to me, I suggest him to do uttarbasti treatment of Ayurveda before also GUI treatment. Sometimes patient not need to GUI treatment also they can get conceive naturally. I would suggest him in this stage to take SIDA Cordelia powder 5 mg with milk two times before food. Since this is prescription base medicine, so you should consult Ayurveda specialist doctor. </s>
