I used it 2 cycles. The first cycle we just put it on DH around OD, never inserted it that cycle and no luck. The next month I inserted it, small amount, the day before OD and only that one time that whole cycle and became pregnant. I am not 100% sure the preseed is what did it but if I was ever ttc again I would definitely use it! Its also just a great lube in general. Good luck!
