Help!!!

So i went on 29 march to register to GP, and the secretary there told me i have to receive a letter home as i'm in the computer so i can book appoiment. Until today i didn't get any letter. Now the problem is, my cousin is pregnant aswell and she told me she made analysis and turned up she took a virus toxoplasmosis. She doesn't know if before or after. So thing is she scared me now, i'm 8 weeks pregnant.. And until now i have been taking Pregnacare and i took care about what i've been eating. I had just some cramps from time to time but no nausea or morning sickness at all or vomiting. My question is cuz i don't know is my first pregnancy, i should go hospital for blood tests, analysis, or scan?? Without the GP? Until it solves.. And does anyone have any ideea how much all this will cost? Thank u!
