Blood Compatibility ?๐Ÿ’‰=๐Ÿ‘ถ๐Ÿป?

Aja
So I found out my blood type is O+ and my SO is A+ and we've been ttc for 6 months now and still nothing. I've read that our blood types have a harder time trying to conceive. Is this really true? Has anybody had this happen to them? What did you do to get pregnant?
