Been tracking periods for well over year now, normally come on time (+/- 2 days) LMP was 8-19-10... on 9-22-10 spotting ( not even enough for pantyliner) nausea, dizziness, but 4 negative test (including dr given urine test).

Wait another week or two. If no positive test then and u still haven't gotten period go to doctor and ask for a blood test. Good luck

Have now Completely missed October period, Still getting negative pregnancy test. Making an appt with Gyno next week!
