Did PreSeed help you get your BFP?

Just wanting some advice/encouragement!  Seems like all my friends are announcing their pregnancies and I'm over here like uh, congrats...now when is my turn?  Ok here goes.  
Currently on CD 19 and had my positive / peak OPK on CD 17. Hubby and I BD on CD 14/15 (it was around midnight), CD 17 and CD 18. On CD 17 & 18 we used PreSeed.  
Do y'all think we have a decent chance at conceiving this cycle?
