So this morning I would've started my cycle so I took a test and there was a fl . I was so geeked jumping up and down because it was a clear faint line . 
A couple hours later I've been cramping like crazy and started bleeding not as heavy as my normal period but in the middle , not light but not heavy.
What's going on? Any help ? I will be taking another test in 2 or 3 days to make sure but I'm so confused .. Is it implication bleeding ?
