Am i pregnant?

Hiya

I finished the pill at the end of the packet, had my usual pill induced bleeding.

Three weeks later i had a period that lasted 3 days.

6 weeks later and i still havnt had another period! Starting to worry as i have had protected sex since coming off the pill (condom) and always check for rips or tears.

Is this normal? Should i wait a bit and see if a period comes or should i do a pregnancy test?!!
