Crossing UK border with EFP in old passport

[Tushka]

Hello. On 12/04/19 l’ve received my EEA Family Permit visa. However now I’m worried that I may have problems at the passport control in the UK during my first trip. As I applied for a visa with my current at the moment passport that has my maiden name. Later I had to apply for a new international passport (takes 2 months in my country). Therefore I’ve got as my traveling documents: annulled old passport with maiden name and FP visa, new passport with married name, translation of marriage certificate. By the way my last name in new passport is spelled a little differently to marriage certificate due to translation rules in my country.
Could you please advise regarding my situation, as I have less than 12 days left before my trip.
