hi fancy, you tried talking or emailing your doctor of your concerns? as for home remedies, i tried accupuncture. i have a friend who had a recent thyroid surgery and after various accupuncture with a chinese doctor in clementi area, she got pregnant naturally. i dunno this doctor's name though.
i have read on high level of bean based food intake (soya-bean, lentils) might influence one's body to have higher level of estrogen, leading on to matters like endo if liver cannot flush out excesive plant hormones. Not sure how true this is. Best, still talk to your doctor.
I was vegetarian for 2 months too - no bean based, no meat, no fried stuff, no biscuits, no vegetables that are white (eg. chinese cabbage, kimchi) or cold water.
