I was that way with daughter. I found out I was pregnant 2 months before turning 46. I had long since given up on ever being a mom. My first OB appt, I was told to not get attached bc I'd miscarry before the end of 1st trimester. I had 3 previous miscarriages and this time I was almost 46. Then when I didn't miscarry, the genetic counselor told me my odds 1:11 for trisomy 18, 13, 21. So it wasn't until 3rd trimester that I actually thought, "hmm, I might actually bring home a baby". And I did! She's a healthy 5 year old now. I hope this is yours too!
