Traveling and fall pregnant???

So I’m in Australia until March. Earlier this week I took a pregnancy test and one test said pregnant and the second one said no. A third test had a very faint positive line. I don’t have insurance so how do I go about finding a doctor to help confirm this? I asked a local who wasn’t too helpful because they suggested I go to an ER. HELP!

In Mackay.

Appointment made but I forgot to ask how much it will cost. Any idea? I don’t have Medicare or travel insurance.
