So... on Sunday morning around 4/5 AM me and my boyfriend got a little excited. I'm not on any form of birth control. We started to have sex but had no condoms, and half way through before either of us finished we came to our senses and stopped. I took ellaone emergency contraceptive on Tuesday.

Only problem is on Sunday it was marked as my most fertile day.

What are the chances of me being pregnant? Anyone been in a similar situation?
