Need help here, I had very light bleeding, like I didn't even need to use a pad for it for 3 or 4 days which is very odd to me because normally my period is heavy and I have to change my pad 2-3 times a day. So, does this mean I could be pregnant? I haven't taken any tests and I just want to be sure its possible before I get psyched out about it. I have been feeling nausea as well.
