Hi, I also tried tian yuan xiang's pregnancy plan. My cycle is about 35 days, I drink the "before ovulation" flavour after menses all cleared (about at 7th-9th days) and start to drink the "after ovulation" one after I'm sure I'm ovulated (usually I use ovulation test paper to test). I found that I got pregnant after trying this way for 3 months. When I'm taking pregnancy plan, I also let my hubby tried "chicken essence for men" to boost his energy and nourish body.
