Brown spotting two weeks before period is due.

Hi all,

I finished my period two weeks ago and two days ago I went to the bathroom and saw some spotting, it was brown. I still have it but it hasn’t changed colour and is only very light. If anything my period is usually slightly late but has never been early. I’ve been a bit under the weather and nauseous. I would just like to know if any one else has experienced this?

Thanks x
