Herbs are not good for pregnant ladies. they have too many estrogens. My daughter took NO herbs when she was pregnant. Take Mgo2 in some form and keep those bowels open and do more... like liver cleanse after the baby. I think you can see if MgO2 is ok with preganancy from one of the companies... I will see if I can find it by tomorrow. Colosan is one product and Oxypowder is another but I don;t know if you can get anyone on the phone with either company who has those products to say yes take it if you are pregnant. Or go on Vitamin Shoppe and search for Mg O or magnesium oxide and see what company has it there and call head quarters first. There is one at VIT. SHOP who has it but I do not recommend it cause it is not as good as the other two. Of course if you want it quick and VIT shoppe is near you then use there's until you order the others on the net.
