okay so, i've been on my depo shot since i was about 15 (i am now 20). i'm supposed to go back for my shot Aug. 1 - Aug. 15. my fiancé and i are planning to try for a baby around that time. well, we have unprotected sex 2-3 times almost every other day. i haven't had a period since last year. i've been having the worst periodlike cramps EVER, it's so bad to where i cannot stand up/move. i also had a real sharp pain going up my left side along with the cramping pains. i've been super moody, craving thing i usually don't crave, headaches for days upon days (medicine doesn't help it). my lower back had been killing me to where i cannot lay down period. everyone keeps saying "you're pregnant". i denied it because of my depo so i told them "no, it's impossible". well, i got tired of everyone saying i am so i decided to take a test...the test looks like it has a very faint line. i seen the line almost clearly when i held it at a certain angle in the light. i tried taking a picture of the test & i could hardly see it, i sent it to a friend & she said she seen it but it looks super faint. i plan on taking a test within a next couple days...i just need some opinions.
