I saw my period on the 5th of march and had sex on the 19th/20th of march and took postinor 2 on the 20th of march, I took the two tablets at the same time which was 16hrs after I had sex. He used the withdrawal method tho but still used the pills incase any sperm entered. I haven't seen my period till now and am really worried, I started using yeast infection drugs on the 28th of march. Please reply me as soon as possible as am really worried.
