Yesterday morning, my girlfriend and I had sexual intercourse with a condom lubricated in non-oxynol 9. Her menstrual cycle began on june 4 and ended on june 7. She doesn't know for sure when her ovulation schedule is (she didn't know how to find out for sure, though I have read a doctor can help her find out), though I have read it is typically 14 days after the beginning of her period.

I pulled out (we were going to move around) and noticed the condom was broken. I had not ejaculated yet. I noticed there was some preseminal fluid on the tip of my penis, but it looks like the non-oxynol 9 came in contact with it, because it looked kind of "soapy."

there wasn't much, and it is possible maybe there was some that got inside of her, I would imagine.

We were not using any other form of birth control, only the condom.

We are discussing whether or not she should get the emergency contraception pill.

Given the scenario of the type of condom used, her menstrual cycle, and the spermicide coated condom, what are the chances of her becoming pregnant and should she look into getting with a doctor about the emergency contraceptive pill today or tomorrow (2-3 days after intercourse, respectively)?

Thank you for your help
