Dear Sir, I have been taking Dronis 20 for the past 5 months. A few days ago, an relative of mine gave me an Ayurvedic digestive medicine called "Salsa," which I am currently taking. I take it 30 minutes after taking Dronis 20. Could that cause any problems? I mean, can this Salsa reduce the effectiveness of Dronis 20? Today is my 14th day on the Dronis pill. Is there any chance of pregnancy here? And today I had unprotected sex, so is there any chance of pregnancy from these things? Do I need to take an emergency contraceptive pill? My period started on the 5th of this month and ended on the 10th. Sir/Ma'am, please reply.
