Positive result..

So I've taken three tests.. just to be sure! I won't get an appointment with the maternity unit until I'm about eight weeks.. my doctors said that only a midwife can answer any questions I have and I have to wait for a call back.. I just want to make sure I'm doing all the right things, and I don't want to do any harm/cause any health problems before then. Any advice would be really appreciated..
P.S not a drinker or a smoker
