Oh I replied in your other post but I'll post here too...
Like I said, 4th attempt of at home insemination we fell pregnant.
The first 3 times we did more inseminations but the 4th time which worked we only did it the one day before I ovulated and it worked. Doc told me not to do it too many times over short period because the semen wont be as potent, will be more diluted with less actual swimmers in it cos there is not enough time for them to build back up. Also he should abstain from ejaculating a week before the deed.
I was taking my temp religiously every morning, documenting everything. Used OPK's throughout the month, checked my cervix everyday for the changes (this was the key thing which definately helped in knowing EXACTLY when I was ovulating) & we used a speculum when we inseminated too.
Hope this is the month for you, good luck!
