I had sex with my girl friend on Friday (the 3rd) and her period is suppose to show up either really late tonight or tomorrow (6th or 7th). Shes been on the pill for almost a year and she never forgets to take it. She takes it at noon every single day. We don't use condoms because she doesn't like the way they feel.

Anyways, on Friday we decided to have sex pretty quickly before going out to see a movie. We had sex the day before and as I said, we did it quickly this time so I didn't ejaculate very much. Even though shes on the pill we still don't like the idea of me ejaculating inside. I think this time I might have pulled out slightly too late. I definitely ejaculated outside her, but it felt like I might of gotten a really small amount inside her as I was almost out of her while pulling out.

She reached inside and pulled out her fingers and no sperm was seen so then we went in to the bathroom and I had her open herself up so I could see better. I didn't see anything that looked like semen so I asked her to push to see if any would come out and nothing came out.

So I basically want to know what the chances of her getting pregnant are if

- Shes been on the pill almost a year and never missed it a single day (always takes it at the same time too).
- I didn't ejaculate much.
- If I did ejaculate inside her, it would have been very close to her entrance and not deep inside.
- Right afterward she urinated and took a shower.
