A little tmi. But needing some advice.

I had my period for one day two days ago and it was there for the day and disappeared at night time. I have had nothing since then except brown spotting, like very light brown spotting yesterday night and now this.

It is watery and stringy and is a very light red/pinkish colour and I am unsure of what is happening.

I took a pregnancy test and nothing as of yet. Thinking it may be my period coming back but it’s never looked like this before and never been watery red/pinkish.

Thoughts?
