Nervous.. Am i pregnant?!

So I'm on cd 27 I usually have longer cycles around 33 days and unaware whwn i ovulate. So I'm due for af in 7 days. On cd 24 I woke up and went to the toilet and wiped to find small brown flecks on the paper. Later that day I had a light pinkish tinge to my cm then went a light pink/brownish colour and about the amount of a 20c coin at the end of the day. For the past 3 days it has been a light brown and very small amounts. So I'm just wondering if anyone has had this and turned out to be pregnant?
