Preseed! To use or not to use!?

Carry • I’m 33. Stay-at-home-wife/Homeschooling momma. Had a blighted ovum in May 2017. Had a little girl in Aug 2018 and May 2020! Overcome infertility on both sides. Prayers and sticky baby dust to y`all!
My follicular phase is actually 20 and luteal phase 12. I will ovulate on June 16, 2016. I have already bought the preseed. How many cycle did it take you to get your BFP, while using preseed?
I would really love to get pregnant this cycle because my husband turns 31 this month and I believe that's the best birthday gift I could give him.
