Bit of background: DH has been working away a lot this year. Last Friday he got home after the latest stint away (2 months) and we got a little carried away DTD....twice. Both times DH managed to pull out before full on ejaculation but said "shit that was close" 
Hormonal contraception doesn't agree with me, /so we usually use condoms but were careless - and since checking my period tracker, last Friday fell during my fertile days.
We already have 2 DCs with a pretty small age gap between them, so would plan to have another baby right now, but if it happens it's not the worst thing in the world.
So I guess what I'm really asking is how likely is it that I could get pregnant from pre-ejaculate during my fertile days? Or has it happened to anyone?
