3rd pregnancy. Just found out. Is this normal?

[Jj2431]

Hi. Just found out I'm pregnant with my 3rd baby. I was 11 days late (not unusual for me) but felt different so tested and got a positive this morning. Feel bad but I nearly passed out with shock so the kids already clicked on (they are 10 and 6). We have wanted a 3rd for so long and always wanted 3 but now I'm pregnant I have mixed emotions. I'm excited to possibly have what I've always wanted but I'm also scared of symptoms appearing like sickness, scared of miscarriage as I have pcos, scared of labour and possible complications. Scared this baby will be crying 24/7 and have health issues like my last child when he was a baby. I don't drive and live a way from the school and I wont move the kids as they are thriving (we are hoping to move house soon anyway but added stress of moving with pregnancy/newborn). Also, my two kids have the most amazing bond, they have their own rooms and youngest will now have to share. I'm so worried but so excited. I keep crying as I don't know how to feel. I will be keeping baby regardless.

Congratulations I can understand how your feeling I miscarriage 7 years ago I expected that I had 2 perfect children and was told I had pcos so I never expected to full pregnant fast forward 7 years I got the biggest shock of my life I'm currently pregnant and it took me a week or so of walking around in a daze once it sank in I started bleeding this was going on over 3 weeks then got to my 12 week scan and everything's was fine then I got a call I was high risk for Down syndrome on my combine screening so did the harmony test and that came back low risk, this baby is so wanted that I feel I can't relax and enjoy being pregnant as I'm scared something will go wrong.
