Hi...the 3rd of July, my period finish, I had sex on that day and took Postinor 2 tablets. I also started a new pack of Birth control pills (Yasmin)on that day. On the 9th July, I had an yeast infection so I took Mycosyst. On the 10th July, I had sex and I took Postinor 2 tablets again. Yesterday the yeast infection flared up and I got suppositories. I took one yesterday morning. I am wondering if the yeast infection tablets affected the Birth control pills and P2 tablets? and is there a possibility of pregnancy? Thanks.
