Blood work and first scan

Seham • Pregnant with #1 👶🏻 🍼 Due January 2019

Hi ladies, went to my doctors after a positive FRER. She calculated that I’m 4 weeks and 1 day pregnant today. She also gave me a referral for blood work but recommended waiting a week before getting it done. She also said there’s no point doing a scan until I’m 8 weeks along.

It’s Hubby’s birthday on Monday and I’ve booked a domestic trip. Would you get the blood work done before or after the trip?

TIA x
