Hello everyone, I'm on day four of my period and the test is positive. On what week should I take medication abortion pills? Should I count from the last period? Roughly in the third or fourth week for good results? And can you tell me if I need to take Mifepristone after taking Misoprostol? Do I need to take Misoprostol after 24 hours or 48 hours? Which one is better?
