preg or not,,,

amanda

ugh, so frustrating. so my last period as 12/9.( 15 days late as of now) I spotted for 1 day on 12/30( period or implant spotting?) period should have came around 1-12 but it didn't. I've had some mild preg symptoms, 2 neg tests about 10 days ago and now today I've got cramps, back pain and light spotting...is this a period or what?
