How soon did you know?

I'm potentially imagining things as I can only have conceived a week ago - and we had one chance at it! - so, odds are i'm just hoping for too much. However, I've had very noticable cramps and bloating for the past three or four days ( my period isn't due for two weeks) My breasts are sore and I FEEL like i'm pregnant. Would it be possible for me to detect conception / implantation like this or is it all psychosomatic because i'd really, really like to be...?

DD no idea till 15wks

DS1 just felt pregnant, did test and was!

DS2 DTD on sat night, Monday all day, metal taste in mouth all day, so just knew...had to wait 2wks before AF due to test!

Ds I had no idea until my period was late and I tested. I did have symptoms but I had been trying so long and got my hopes up so many times I didn't dare think about it. With dd, 8 days after the deed when I ordered steak at a restaurant and ate the salad and chips and left most of the steak (unheard of for me, salad is something that rabbits like)
This time I was sure from the moment they put the embryo back, I could feel it. Sounds a bit woo I know and I'm not normally a woo person at all, but I could feel this vibration like someone else was there. Not physical at all, but very much there.
Second two times I got positive tests way before my period was due, 4 days early and 6 days early respectively.

I knew before my period was due with dc2 as my cheeks were really flushed looking and I had the metallic taste, with this pg I was sick 2 days before my period was due so tested and got bfp.
