Scared

I am so paranoid something will go wrong ... My job is aware I think I'm pregnant and I'm going to the doctor this Thursday to confirm !! I took 6 test and line is getting super dark no control line barely there.. But still I'm paranoid what if I'm not!! I mean I have nothing sickness all day I throw up white foam ... My breast are sore to the touch ... And nipple swollen !! But still paranoid anyone else
