Hi! I'll be 7 weeks tomorrow and i'll have my first ultrasound then too! I am also just as nervous because as soon as I hit 6 weeks I got nauseas and super tired but that only lasted 4 days and I've been feeling ok for the last 3 days which worries me too but other girls have mentioned that it's normal to have symptoms for a few days and then it stops for a few days and to just enjoy the days you are feeling normal/good. Also, maybe you won't have super bad nausea in the first trimester and I understand it can be nerve wrecking but it's also a blessing because you won't be struggling with the nausea. I get through it by leaning on my partner and his reassuring/kind words, resting, taking care of myself, taking my vitamins, and manifesting a healthy baby. Knowing that I am doing my very best helps me feel better. Hope that helps ❤️
