It is much better if you first cleanse your body, and then go on getting pregnant.
You can't do full parasites cleanse if pregnant, and you can't putt as much energy in cleansing if pregnant.
You do have some symptoms that point toward blocked liver and liver stones , and you should cleanse before you get pregnant, or if you already are pregnant, you should immediately start with enema, and after few enemas you can do several liver flushes.
To get some ideas, read messages in Pregnancy Forum, and read also Liver Flush FAQ .
