Hello and welcome,
After rupturing the ovum stays available for 36 hours for fertilisation. It is impossible to say when the follicle ruptured. But we must use the 36 hours window to help the sperm meet the ovum. Most of the time the follicle is ruptured already when IUI is done as HCG
is given to rupture it only.
So do not think so much about it. Get the IUI and wait.
My best wishes are with you.
Hope this was helpful.
Feel free to ask any further queries and I will be happy to help.
Thanks for using HCM.
Have a good day.
