Spotting/Bleeding

Karen
I know it is sometimes common to spot or bleed in the first trimester. It just scares me to death. Initially it was brownish then bright red one time. It's been going on since I woke up. Light cramping but I have had it since before I even knew I was pregnant.(the cramping) I also know being only 5 weeks 3 days there isn't a whole lot anyone can do. I'm going to wait until tomorrow to call the doctor as I had spotting with my first two. The only difference is with those two it was after having sex, this was unprovoked. Any opinions?
