How early do you get that really tired feeling? Period not late yet, so too early to test, but feel soo tired. I remember being noticably more tired early in 2nd pregnancy, but cant remember at what stage.
I started to feel more tired a week before I tested positive. I remember as my sleeping pattern was totally out, ie couldn't sleep at night and barely any at all but all of a sudden I was sleeping at normal times again.
One of my pregnancies I was absolutely shattered at about 3w so obv I didn't realise I was pregnant but a week later when i got a positive HPT, was able to realise why I'd slept through an entire weekend.
With the other pregnancies I've not really got tired until later on, but as they always say, every pregnancy is different.
