Hi Amber- thanks for this important question. We cannot provide medical advice on this site, so would encourage you to ask this question of your doctor (preferably a migraine specialist who has experience with Botox). A preliminary check of internet resources seems to show that there have been no well-controlled studies of Botox use in pregnant women, and so because we can't be sure it is safe during pregnancy, it is not recommended. Again, however, this is a question best discussed and weighed with your physician. Thanks so much for being a part of our community! Please stay in touch.
