im in my first trimester and I have been really sick. I went to the doctor last week, Tuesday and they did blood work and I got really weak and sick afterwards. I started having this pain when I had to go pee and then after I used the restroom the pain went away. Along with the pain I will walk a short distance or b on my feet a ver short amount of time and I will be exhausted, then I will be extremely cold but everyone else is warm. I wanted to know if I should go to the doctor or ER or anything because I'm also under stress with me job although I don't do much at work im bring called in on days I usually have off.
