birth control freaking out my brain ?!??

ok so my entire life i’ve been pretty boy crazy, lost my virginity two years ago. i recently started birth control again two months ago and it’s like fucking with me. ever since i started it i’m like turning asexual? like clearly i’m straight and sometimes i hookup with my ex and it feels really good just the whole time i’m having weird thoughts like “this is what i like idk why my brain is telling me different “ like my brain keeps giving me thoughts of me like not wanting men and maybe thinking i’m lesbian? but i know i’m not cuz i’m not attracted to girls and seeing two girls kiss and stuff doesn’t turn me on. Like i’m not sure if i’m like this cuz i’m just not into my ex anymore, my horrible anxiety, or a decrease in my sex drive due to birth control. Like i know i love dick and men but my brain is like “no you don’t” with stupid thoughts after starting birth control again UGGG WTF! someone help
