DEPO SHOT SEX DRIVE

i’ve been on the depo shot for probably 6 months now and so far it’s been good, no periods but putting on a bit of weight but that’s not what is irritating me, my sex drive has completely disappeared and that’s not like me, before the shot i thoroughly enjoyed sex often with my boyfriend but now i wouldn’t even bat an eyelid and it’s so irritating!! for me and for him, does anyone have any tips on how to get sex drive back without going off my contraception !???
