I had unprotected sex last 30 Oct 2008 at 11 pm until 1am of 31 October 2008. He did not ejaculate inside me since I finished him off by hands long before his ejaculation. I took 4 tablets of Nordette when I got home around 2 am (31 October 2008) then took the next 4 tablets almost 12 hours after that (11:50 am 31 October 2008).

FYI. I think I am fertile when we had intercourse. My last period was October 15 to 21, 2008.

1) What are my chances of pregnancy if I had unprotected sex when I was fertile although he did not ejaculate?

2) I am not sure if there was precum while he was inside me. Could precum get me pregnant? By the way, he urinated before we had intercourse, does this lessen chances of precum (if any) getting me pregnant?

3) What are the chances of Nordette preventing any possible pregnancy given above details? If effective, should I expect my period before, exact date or after my expected next period of 17 Nov. 2008?

Urinated, does not effect aything

If you were having sex he will have precum, and there are plenty of sperm in precum long before he finishes.

I am not familiar with Nordette is it one of the approved morning after pills?

But none of them are 100 percent,

I got pregnant with twins from precum. So yes you can.
