Pre-Seed

I was wondering where I could buy pre-seed and why it's better than conceive plus. I'm wanting to know because I want to buy some and try it out. So my hubby and I can have our 🌈👶🏻. I had 3 miscarriages and I want to see if this will help me. If it does I'm going to be very happy. Also does pre-sees have instructions that come with it so I know how to use it and if my husband uses it too. Thank you.
