Hello friends. I have no idea what to do. I thought I started my period last week. It only lasted for one day. This has happened to be before in the past. What is different this time is what my period blood looked like. It was so weird. It didn't look like normal. I don't know how to explain it. But it wasn't like any other period blood I have ever had. Could this be implantation blood? When should I take a test? It had been 7 days since then.
