Unfortunately I think I'm experiencing a chemical pregnancy. I had some brown spotting start last Saturday that lasted through Tuesday and I NEVER have spotting between periods. I thought it was implantation bleeding so I took a test on Sunday morning and sure enough, that second faint line appeared. I didn't believe it so a took another one Sunday night and it was another faint second line. I took a Walmart cheapie on Monday and got another faint second line. I stopped spotting yesterday and then today, started bleeding pretty heavily about an hour ago. It was very early. I wasn't even supposed to start my period until this Saturday and today we technically would be 4 weeks. Has anyone else been through this?
