Girls, hi! I'm still not giving birth yet) They're going to stimulate me at 6 am tomorrow. I have a question: I took laxative suppositories to cleanse myself before childbirth. And I'm thinking whether to take them at night or can I start taking them at 10 am already? I think I will only eat lunch and dinner probably won't be eating, just drink yogurt so as not to spoil the whole room with it ???
