ok im 19 almost 20 and i been on the ortho evera for about a year in a half and last week i spotted and it was very light and light pink, it went away in like 2 days. i started having back pain and i had to use the bathroom a lot and sometimes i would fell a lil sick but very lil. and this happend a week before i was goin to get my period. so next week came and i started bleeding but i started to spot before i started and that has never happend before till now and i think its my period but its lighter then wat it normaly is. so is it posible that im pregnant or is it all in my head?
