Nobody likes feeling unwell, yeah i didnt feel really bad through my first trimester but i have a stomach disorder that i have had for 2 years! and i feel like rubbish 70% of the time and it wont go away as its permanent!! whereas this isnt permanent for you and when you get into the second trimester u will more than likely feel better.
So just relax and remember there are women out there who would die to be pregnant and cant so you are lucky.
You have a baby already so u know its worth it dont u and it wont last
