Could you be pregnant if your period was normal in aug and in sept your period came 4 days early and it lasted 2 days and was pink and brown and took a pregnancy test two weeks later and was negative?

You could be pregnant. Home pregnancy tests aren't always accurate, if you are worried and experiencing other pregnancy symptoms then call your gyno. I am going through the same thing as you right now with the spotting of pink and brown which lasted 3 days for me and i have the nausea feeling. But with me I am on the mini-pill and I take it every day at the same time, like they say. :-) I took a hpt and it was neg. I am waiting 2 wks. and taking another one and then probably calling my doctor. Good Luck!!
