Pregnancy scares?

Katie
I just need to hear some stories. I have anxiety and I'm convinced I'm having implantation bleeding. If this is my period (I am supposed to have it this week, it's my placebo week) it's very light. It started with light pinkish/brown blood. This morning it was red but now it's light brown again? I have cramps, no other symptoms beside being bloated but that's always been the norm for me. I was nauseous yesterday, but that never happens to me when I'm on my period. I'm try to tell myself this is my period but I can't calm myself down. I have been kinda stressed this last week so maybe that's it? If any of you ladies have some reassuring stories/advice I would really appreciate it. And please don't tell me to test because I'm planning to on Thursday. I just want to give it some time in case it shows up...
