Hey girls; so I'm 18 years old took two pregnancy tests last Friday and they both came back positive. I went in on Monday for blood work and I now have to wait for the 15th for my results. So since I have to wait so long to see a doctor then even longer for a baby doc lol I'll start out by seeing what your opinions are on this question...
I'm a welder, doing that in school and got accepted for welding in college. I asked my welding teacher because he's a family friend and he says it's okay just no Tig welding (too high of electric shocks coursing) and be careful of my temperature and always have the ventilation running and doors open. 
What is your opinions about this ?!
