Light bleeding after faint positives??

Hunter

Took these tests 3 days ago. Both were very faint. So I decided to wait a little longer and test again. This morning after work (I work thirds) I had some extreme nausea spells, literally sat over the toilet half the morning. Then I started getting some pretty bad cramps. When I wome up tonight, I realized I had some light bleeding. Is this a bad sign? (These are from a previous post of mine)
