I got AF on the 15th and finished on the 24th. We DTD last night and usually he pulls out but he didnt.

I don't really understand how it all works considering it only took one oopsie to concieve DD and by my calendar it was the day after i ovulated.. and going by an online calender yesterday was a fertile day but thats going by a 28 day cycle which generally mine is but this AF was 3 weeks late so im not sure if its still corrent IYKWIM..?

I heard that sperm can live up to 5 days up inside so is there a chance i still could concieve... i feel like such an idiot i just have no idea about this stuff.
