I've been bf my 3 mo son, and have been supplementing 3x/day at dr's orders due to his slow weight gain. I seem to have a low milk supply, athough I am pumping after feedings and taking fenugreek. From what I have read, progestin only pills shouldn't affect milk supply, is that correct? I am also taking prescription allergy meds, Allegra-D, which have antihistimine in them. Could discontinuing the Allegra-D increase the milk supply? I am also taking Flonaise, which is a nasal spray for the nasal allergies but I don't think it is an antihistimine, so I may be able to get by with only using it. Thanks for any input!
