Hi. Great idea. Forget social and forget search. Middle-aged women won't search or share this. I found the same thing with an IVF test product I have worked on for a California-based company. My advice would be to list out all the available marketing channels and tactics open to you and eliminate those you a) can't afford, b) are not direct enough or c) require sharing P2P. My guess is that you'll find that your best ROI welcome from advertising on related websites. Good luck. Happy to help further. Mark
