How many weeks am I? (Doc appointment question)


Hi ladies. So my doctor has me coming in tomorrow for my appointment. I will technically be 4 weeks and 4 days. Is this considered 4 1/2 or could I round it off to 5? My ovulation was super late into my cycle and I’ve already had one appointment before 10dpo, where they didn’t see anything (obviously) Going in a week later

is a little nerve wrecking so I’m trying to determine more or less what to expect and not panic.
