Loestrin 24 Fe and bone mass

hey, this is my first time taking the pill ever!!!! i was on theshot almost 2 yrs ago after i had my daughter for about 2 yrs that was cool no weight gain nothing:) but then my doc told me she had 2 take me off because the hormone makes u lose bone mass(yikes!!!) so 2 yrs later i back at it with loestrin so far so good. my period is ramdon i spot here and there no acne thank goodness. i always had depressing moments i don't if i'm having more or this is jus regular ol me crying, lol, but anyway i sorta like it im stick it out until i can't take it anymore. i think it may just b how ur body reacts to certain types of bc, bcuz i kno that my best friend had major issues with her body when it comes to bc but me 4 the most part i'm cool so i goona stick 2 it until then!!! peace
