Is there such thing as too much pre-seed?

Last month we used pre seed for the first time (was also our first month TTC) and I used the recommended amount via syringe and also some of that topically. But I swear it almost like numbs you or something!!! Anyways we didn’t get pregnant (not claiming that’s why) but I am wondering if maybe there’s too much of a good thing with pre-seed. This month we are only going to use it topically. Any insights into this? How did you use it / were you successful?
