Conceive Plus vs. Pre-Seed/PregPrep??

MicMiller33 • Mom to 2 beautiful girls, Kirsten- 3 👧🏼 & Lena- 18 months 👶🏼, baby #3 due September, 2020 💜💜
Does anyone have experience with both or have gotten pregnant using one or the other? Just about to embark on our 6th month TTC and have been using conceive plus. Thinking about switching it up next month. Any advice is appreciated!!!
Also... Has anyone used or is using PregPrep??
Thanks!!
