First prenatal appointment help

Haley

I got my BFP today and I called to set up an appointment and the receptionist said they like to see patients when they are 7-8 weeks. Well based on first day of last af I would be 7 weeks on my first appointment, but I did not ovulate until cd26 with a 14 day LP making my cycle 49 days not the “standard 28.” This would make me significantly less along than predicted by last af. Should I call back and reschedule the appointment using my ovulation day since it is 12 days later than that “golden 14 dpo?” As my appointment is scheduled I will be 5 weeks 5 days. I don’t want to get in there then be told something is wrong when it really is just I had a super late ovulation. Any advice???
