QUESTION ABOUT THE PILL🛑🛑⬅️⬅️

I’m 16 and I’m sexually active, I have really bad period cramps and my period is irregular, so my moms letting me go on the pill. I was reading about it and people said that it can ruin relationships and affect your attraction towards someone. Reading that really scares me and I have been dating my boyfriend for a little over a year now, I love him so much and I’m extremely attracted to him (his personality and looks) but reading about all the hormonal changes going on and how it affects things that like I don’t want to like stop liking my boyfriend. I’m so confused on what happens and how everything works can someone please explain this!!!!
