About 2 days ago I noticed i was spotting and it was very very very light & it stopped last night. But this morning it seems like i have started my period. But Im having no cramps, im not moody & my breasts arent swollen. (all this usually happens about 3/4 days before i start) Ive never had this spotting before & all these symptoms happen to me every month, Ive never missed it. & all day today ive had a horrible headache, im very tired and my lower back hurts. Could i be pregant? Or am I just making myself think i am?
