Wasnt sure about keeping the baby..how far behind am I?

Today is officially the last day of my first trimester and I wasn't sure that I was keeping the baby until just this week for so many reasons but anyhow I decided I am keeping the baby after all. Now I'm just worried about how far behind I would be on all the prenatal testing. I'm starting to stress out about what if somethings not right with the baby. I made an appt. for next week but I'm still just worried. I know that I probably would have had the AFP test I believe and I know how sensitive that test is regarding down syndrome. Do you guys think I'll be okay or the baby will be okay. I had an ultrasound done on 1/31/09 and I was 9 wks 1 day because I had spotted a lil bit and the Dr. had said the baby looked good and measured perfect but still that doesnt mean anything. Also another thing that worries me is that my bf and I have o blood type. I'm not sure if I'm O + or - and neither is he but do you think us having the same blood type maybe will cause something to be wrong with the baby or does our blood types have nothin to do with it??
