First Docs visit at 6weeks

I was wondering if anyone is in the same situ or can offer some advice? This is my first pregnancy. I am 6 weeks pregnant and had my first GP visit yesderday. I had two positive pregnancy tests at home and another in the doctors office yet today for re-assurance i did another (im a worrier!!) which was negative, ive had no morning sickness, boobs arent too sore and ive had cramping and discharge. Im waiting for the Early Pregnancy Unit to call me but Im slightly worried now. As I said its my first pregnancy so im not sure what i have to do, whats normal, whats not etc!!
