Hey Tink! Congratulations on your great results O+ is the most common blood group, something like 40% of the population have it. So I guess it's a good one to have! LOL

And yes, the worry is completely normal. I've been a major worry wart since becoming pg. Just hanging out for the 12 week scan and that everything is ok! Hopefully you can stop worrying now and start enjoying your pg

Love
