Can your blood group stop or affect conceiving a baby?

Hi, I just wondered if anybody can help me. I was watching a programme recently where a woman had miscarried her child due to her blood type being “0”. I’d never heard of this before and has anybody had this before?

I’m A Rh- and wondered if this is why I haven’t yet become pregnant after 1year and 4 months.
