when can i take a test?? very confused.

Hello I am new to this.. really need some advice. My last period was on the 10th Sept. So I started my mini pill on this day. Then on the 9th Oct I forgot to take my pill. So since the 9th Oct I haven't taken the pill... then on the 12th Oct started with very small amounts of brown discharge then it stopped on 14th oct.... had sex every other day. Been bloating every evening i look pregnant...head ache. Can't stop peeing very tired aswell.... and cant stand the smell of beer too!! I was pregnant August I was 7 weeks and misscarried... any advice would be helpful thanks.
