Only 13 weeks...

Not sure how exactly I’m suppose to get through this pregnancy especially with a baby who’s starting her terrible twos. I feel nauseous 24/7, I’ve lost 10 lbs as I can’t eat, my boobs have grown 2 sizes, they are extremely sore, I’m constantly running to the bathroom, I’m home alone as my hubby works away during the week and my baby constantly needs to be up or attached to my him and constantly think she needs to jump on me. I’m trying very hard to stay positive and sane but this pregnancy is really taking a toll on me and I just really want to cry and lock myself in my room and lay in bed for the next 27 weeks :(
