Conceiving 9 days before estimated date of period?

I know it's possible, but I wanna know if it has happened to anyone and how early did/can you test if so? Thanks again ladies!  

I think it's possible if you ovulate late. You can test roughly 10-14 days after ovulating to recieve an accurate result. It also depends on what kind of test you use.

Thanks   That's just the kind of info I needed!

I have about a 30 day cycle, i usually ovulate anywhere from days 14- 18. Well I got pregnant this time on day 30! Dont know how but I did!lol That was the only day possible to concieve. I was suppose to start my period the next day and never did which is weird because the eggs doesnt implant for like 2 days i think?? Guess it was just late anyways..idk...its weird!
