Feeling tired drained emotional and feeling sick!!

Nikita
Right if anyone can help me I'm 7 and half weeks pregnant and I've been feeling sick for about a week now but I'm not actually being sick so it's making me feel crappy emotional an just not myself because if I was actually being sick I might feel better because it's out but it's like my body don't want to let it out anyone had this feeling? And help with how they deal with it because I'm all ways feelings crap and I don't want my baby to pick up onit😓 also I looked on the internet about sickness and they say it's a sign that the baby's doing well so does that mean my baby's not healthy if my body's not actually bringing the sick up? Please anyone that can help 😣😞😕 thanks
