sesame - the most burnings is done on 1st, 15th and last day, other days also have but not that much. same as u, my gynae + andrologist say our only option is ivf-icsi. but my not so professional gynae say since my tubes are not blocked can try iui, after my 2nd failed attempt, I got no more patience with her and decided to seek 2nd opinion & it was confirmed ivf is my only option
