The cheapest and most accurate way is just to wait for your period date and buy a basic home pregnancy test kit. Don't go for expensive blood tests early on unless your doctor specifically recommends it.
My grandmother used to say feeling unusually tired or having a metallic taste in the mouth are early signs. But a proper urine test after a missed period is the only way to be absolutely sure.
