Period or not?

Hi everyone,

To get things started, here are my cycle lengths since I stopped the pill:
1st: 31 days
2nd: 28 days
3rd: 36 days
4th: 34 days
5th: 34 days
6th: 34 days
7th: 44 days
8th: 31 days
9th: 36 days
10th: 33 days
11th: 38 days
12th: 39 days
13th: 33 days
14th: 39 days

My last "period" felt a bit weird (I don't normally have that much brown discharge). It started on Monday late afternoon with brown discharge, Tuesday and Wednesday had normal bright red bleeding, Thursday was only brown discharge, and on Friday it was very light brown discharge.

Can I just count this as a period, or is it maybe worth taking a test just to be sure?
