Sore back (combination of being in 1st trimester and holding DD)
Extreme fatigue, I could sleep for 12 hours... unfortunately it is not possible with DD
Craving for vinegar
Eating all the time and feeling hungry even right after a meal
Period cramps feeling around 4th week of pregnancy
The need to wee all the time (my gosh, already, imagine when I actually have a huge belly)
A little bloated (people would probably ask me if I'm pregnant because it shows but I think it's gas)

And of course, no period....
