I understand the worry, but 22 plus 5 is still within the acceptable window for an anatomy scan, so you should be fine. The ideal timing is 18 to 24 weeks, and your scan falls right in that range even though it's a bit later than the standard 20 weeks. If you're concerned about the timing or want to confirm that 22 plus 5 works for what your doctor needs to assess, it's worth trying to reach the clinic again when the doctor is back, or asking the clinic staff directly since they handle the scheduling. First time round everything feels uncertain, but you're not behind schedule.
