So I am supposed to start my period today but just haven't felt right so I took a test this morning. At first the line was not there. I came back in the restroom less than 30 minutes later and the line had appeared. I then took another test about 4 hours later that's negative and I started bleeding but not as heavy as my normal period. Do you guys think it's my period and I got a faulty test or should I retest another time? If so, how long should I wait before taking the test again.
