Hi, we're planning ivf abroad (Reprofit) and in the initial questionnaire they've asked for a scan done on cycle day 13-14 to get an idea of lining, any cysts etc. I have cycle lengths from 29-36 days so it's impossible to aim for mid-cycle scan. I'm booked in for this Friday which is day 15 but I'm tempted to move the scan to Monday (day 18). I'm wondering if you ladies know the significance of the scan being day 13-14? To me it sounds like they want just before ovulation, but I'm worried day 15 will be too early and day 18 might be just after. Typical that ovulation will likely fall over a weekend but I'm not waiting another month. Do you reckon Friday or Monday? Thanks for any advice!
