Brow liquid??😫

Yesterday afternoon I had a friend over and I had to go to the bathroom so I got up and went and when i looked down the inside of my underwear was covered in a brown liquids substance. It kind of freaked me out but I didn't do anything about it. Then this morning I woke up and went to the bathroom and after I finished doing my business I felt dropping still so I looked and there was brown liquid dripping after I peed. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I start my period in 2 days so is this normal? Please help!Â
