Trying preseed this month.. any of you ladies had a good experience with preseed?

I’ve been trying for 6 months now.. my husband and I are fertile. No issues. Been using opk’s , taking prenatals , drinking plenty of water , lost weight , started eating better and I still have yet to get my BFP. This is super disappointing I just want to see them two lines so bad 🥺 I wanted to ask you ladies If you’ve conceived with preseed and if so did you have a healthy pregnancy / baby? Any tips for trying to conceive ? I’ve heard of mucinex , preseed , and evening primrose oil to help increase fertile cervical mucus. As far as testing with the ovulation tests … how often do you ladies test a day?
