Thanks for your response Annie.
I'm confused right now, I think I may actually have ovulated this past thursday which was a week after the unprotected sex so guessing I wouldn't have conceived at all.
The weird is I keep getting this absolutely clear discharge that sometimes just comes out as if I'm about to pee myself. I had a similar thing when I was pregnant last year (unfort did end up miscarrying). I don't really believe I could be pregnant, the dates don't seem to be adding up but will take a pregnancy test just in case next week as my boobs are really tender at the moment.
This cycle stuff is hard to figure out and its too easy to misinterpret signs when you think there's a possibility of pregnancy!
Yes, if he ejaculated even a little, there would be sperm present. A single ejaculation contains something like a million sperm or some amazing number like that. So it really only takes a little.
If you become pregnant, it will be on the day you ovulate. His sperm will last up to 5 days in your system, so they're just sitting there waiting for the egg to pop into your tube.
Good luck one way or the other!
