I've had 4 children, in 4 different places, and lots of surgeries as well. Each birth was complicated (c-section with one, PIH with another, diabetes with another, and polyhydraminios with 3 outta four of 'em). But when I divorced my first husband, I wasn't allowed to take my medical records with me. So, since then, I've just verbally told my GP everything, and he's just taken my word for it and made new records with my old history added in. So, if for some reason, you can't
(if it's way too expensive to justify) get your records, you should still be okay in the long run.
