My period Started on 12/29. I had unprotected sex on 1/2. But it was at the beginning of my cycle so I didn’t do anything. I also had unprotected sex on 1/9 and took plan b. I had unprotected six again on 1/11. I am going to take plan b again today. What are my changes of getting pregnant? I was high fertility on 1/9 and 1/11. I’m really nervous.
