hi, i'm also 20, and i lost 2 babies in 8 months on the pill. i was 18 at the time and neither of them were planned pregnancies or even known pregnancies until i knew i was miscarrying. i had never really thought about having kids until i 30 or something but it was the two biggest losses me and my partner have ever experienced just the same. regardless of whether you planned the pregnancy or knew about it until it happened, it was your baby and it's still devastating. i always felt that made it harder tbh. it meant that you had the shock of finding out you were going to be a mother at the same time as finding out you had lost the opportunity of being a mother, which is too much emotion for anyone to deal with by themselves in such a short space of time.
don't let anyone make it feel stupid or act like they don't understand. how you feel is natural given what's happened. nobody will understand exactly how you feel, and it's such a personal experience that i would recommend a bit of time of work to figure out where your head is with regards to your loss.
