I am not supposed to get my period for another 18 days but yesterday when i pee and cleaned myself i had a little blood but just a few spot and then stopped. Today I woke up with heart burn and very very nausea and threw up couple times. Fiance and I use the pulled out method. We Never got pregnant and i never felt this before. Its too soon to feel anything? My last period was the december 25th. Is this even a symptom?
