Preseed experience?!

Sarah • 19|engaged|TTC
So, I've been TTC for a lonnnng time with my fiancé & I'm getting impatient. I've been reading reviews for PreSeed for a few weeks & since I'm ovulating, ran to the store just now to get it (cashier must have thought I was nuts). I just wanted to hear about everyone's experience with it. Did it work? How long were you using it? Did you use anything else? 
Any other tips to help would be awesome, thanks!
