Late Period

Indiah
My period was late by 9 Days. A few hours ago, I felt a little more wet than usual down there. I went to the bathroom and found that I had started bleeding a little. I had been wearing panty-Liners because I had been expecting my period. The unusual thing is that The other times my period was late, it would start brownish, this time it is bright red. I have a doctors appointment on Monday. Do you think I might be pregnant?
