hi janell, i would definitely ask my doc about taking anything, but personally, i wouldnt take anything herbal while pregnant, i dont even drink most herbal teas, nobody regulates the stuff. even if the herb itself is safe, its hard to say what other things might have found their way in there.
if you want to boost your supply, you can try oatmeal with fake maple syrup (cheap-log cabin, etc) in it. the oatmeal (real oatmeal, not the instant, loaded with other stuff kind) boosts your supply, and the syrup does, too, as it has fenugreek in it, but food is monitored so its ok - (though i didnt know anything about it not being safe during pregnancy, i would think the amount in syrup is ok since its not on that list of stuff we cant eat during preg, but i know that now i will ask my doc about it to be sure.) the oatmeal + syrup worked for me when i was trying to boost my supply, made a noticable difference after just a few days, along with drinking a lot more water, and of course, no caffiene or any meds that would dehydrate you. my gyn also recommended beer, specifically black beer, though i dont know if they make it non-alcoholic, i never tried it myself.
im sure you know this, but the best way to boost your supply is to increase the frequency with which you nurse (or pump, though putting the baby at the breast is much more effective).....
also, i dont know if you have gotten your period back yet or not, but if not, then boosting your supply is more likely to keep you from getting it back, though certainly no guarantees, everyone and every preg is diffferent. best of luck to you, and remember that being pregnant while nursing places a big demand on your body, so treat yourself well, eat and drink and sleep really good. take care, D.
