Low sex drive? 😓

So I've been on the Depo shot for about two months now and have had a consistent period for a whole month which is still ongoing. I haven't really had a problem with the period since my doctor told me that was normal, but I've had an extremely low sex drive since I started my period way back on Christmas eve and I feel it's due to the shot. I feel terrible for not wanting to participate in sexual activities with my boyfriend, but I can't even bring myself to give him a blowjob whereas before I would jump on the chance to make him feel good. He says it's okay and that he understands (and I am absolutely so lucky for such a sweet guy). Can anyone else sympathize with this? Or at least give me advice on ways I can pick up my sex drive again?
