Very confused

Charlie

Hi, This is my first pregnancy and I am 2 or 4 weeks dependent on how calculated. I have 2 questions...

1 - if I have had several (very) positive tests do I need to get bloods done?

2 - when do I need to see my GP?

Google doesn't seem to be very forthcoming and the receptionists at my GP are crap and getting appointments when I am working is difficult. Xxx thank you xxx
