hi,i had unprotected sex on 22nd dec afternoon. I took unwanted 72 next day morning at 10 am. I also had unprotected sex on 13th , 14th, 15th and 16th December. I had my normal periods on Oct 19th. On Oct 26th i took an ipill because of which i had bleeding on November 3rd. I have PCOD and took Topomac, gluconorm SR and Meprate in that month. Meprate was just for 10 days. I got my last periods on December 7th. Is there a chance of pregnancy?
