Have no sex drive

So I’ve been dating my boyfriend for about 4 years and I’m the beginning I never had an issue with getting turned on or having a sex with him or with any other guy. Now I do.... I never feel it and even if I try to turn myself on - nada. I was on birth control since 16 (now 26) and recently went off because I thought maybe it’s the hormones messing up and it was no help. The only help was my obyn put me on medroxyprogesterone 10mg tables to help me get back into normal cycles from being on BC for so long and that made my desire and Dax feel normal! Ever since the tables ran out it’s been back to the old ways of feeling nothing. Any advice? Has this happened to anyone before? Would going back on BC help?
