able to get pregnant?

Sara× • 18yo soon to be engaged and getting our first home with my 20yo💖Just bought our first car together and TTC!🙈🙏❤

I'm wondering how do you know/check/ how doctors do it to check if you are actually able to get pregnant. I'm very petite, 4'11 height 73 pounds. When I was younger I used to be anorexic, id hurt my insides and id self harm. Nowadays I regret all that for this specific reason.. I hope I'm actually able to get pregnant. 💔 Been trying for awhile, missed period by 10 days but still a negative. 😔😒
