Early pregnancy symptoms what are they?

Im sure you get this question alot! Ive been TTC for a year now, have had 2 kids before. ATM i feel all wobbly and weak, tired and peeing alot. In the past year ive had alot of imaginary pregnancy symptoms so thats why im dubious now! AF in due sometime this week. I know i should do a HPT but havent got any and dont want to get my hopes up. How did you all feel around the 4 week mark?
