I’m so confused, can someone help me?

Hey girls,

I hope someone can give me there insight into what the hell is going on.

This is a first post here.

My last couple of cycles have been 28/29 days.

My last af was the 4th

Cycle day 19 I started spotting very light pink then went to brown over a couple of days. It was only when I wiped and not every time.

I’m now on CD31

No symptoms really, tired, lower backache the last few days.

Could of this been my period even though it wasn’t a flow and extremely early?

Thank you
