Every get scared?.

Dee
I was on birth control from the age of 16 up until this Jan (I was 25). I got on them because of acne and heavy periods (had to change my pad every couple hours and too terrified to use tampons) any way, now I'm 26 and me and my boyfriend wouldn't mind if we did get pregnant. 
But to be honest I've been scared that maybe I will have problems getting pregnant of at all. I know my body has to regulate itself but how do I know when that is 😔. So far ive had 4 periods and I'm sure I will have another one this month. 
Have you been worried about this?. I know doctors say that nothing is proven but sometimes we know other wise.
Thoughts, feelings opinions??.
