Well, I do think it does hinder TTC at least somewhat, how could it not?
There will still be some effect from the 3 days ago batch but it will be less effective.
Using the applicator a few hours after TTC is too late, sperm leaves the vjj very quickly after intercourse but it will work for future attempts.
It really doesn't matter TOO much, there's no right or wrong way to do it, whatever you do, I'm sure will be just fine! GL
