Birth control???

So i came on here asking about birth control if it would mess with my fertility and a lot of woman had said no & that its perfectly healthy. Im still scared to take it and ive found out something new about birth control that i wasnt aware of but still no suprise. One of my co workers told me that her doctor said girls who are on birth control especially for long periods of time, their ovaries and eggs look old. Like a early 20something woman on a constant flow of birth control her ovaries seemed aged like a 40something yr old ovaries. Im so scared to take birth control because i do want a child eventually...sooner than later actually. Im 27 & would like a child before im 30. I wanted to share this & if anybody has any input or experience where birth control did or did not affect their fertility commenting below it would help. Im still having cold feet about going on the pill😣
