Sorry I'm confused by some of these comments. You don't know if you are pregnant right? If no then I would not go to the ER. If your period is late than I would go get a test and if you are pregnant then I would not worry just yet since the first lady is right it might just be irritation bleeding. Good luck.
I have my doctor appointment on the 6, and I have been feeling good small cramps but before the bleeding started.
If it's bright red, period like blood I agree I would go to the ER. Did they examine you earlier? That can cause light spotting.
First thing is to take a pregnancy test. If your pregnant it could just be irritation bleeding. I had that with several of my pregnancies.
