I am about 5-6 days late and for 2-3 days I have been getting light pink spotting but it only happens once or twice a day and it's only on the tp when I wipe and it's VERY little.. I have been tired these past 2 days, more tired than usual and I'm getting 8-9 hours of sleep every night.I'm getting headaches but I don't know if that is from me being so tired or it's a symptom . But I took I pregnancy test around 8pm and it was a big fat negative. Any thoughts?

Yes,first you are testing all wrong. You should not be testing till you are at least 14 days late. Also tests should always be in the morning as soon as you wake up. So if you wish to test too early, do it, in the morning
