Using pre seed for the first time!

Janis
Hi ladies! 
So I'm using pre seed for the first time this cycle and I'm just looking for great news about this product! And how long it took you to conceive using it. My experience so far has been very slippery 😁 and we have used it twice during my fertility window! Is that enough? Or should we continue until it's over? I'm on cd 15 btw
