If you use misoprostol pills under your tongue, no one will be able to tell you used abortion pills, as you will swallow everything after 30 minutes. If someone asks, you can say you had a natural miscarriage. If you use misoprostol vaginally, the coating of the pill may not dissolve completely for a day or two. If you need to seek urgent medical care within 48 hours since you used misoprostol vaginally, the healthcare provider may see the white coating of the pill in your vagina. This is why HowToUse suggests using misoprostol under your tongue and not inside your vagina.
