@Madamemerle Welcome! This is a good list of abbreviations: https://www.fertilityfriend.com/Faqs/Common-Abbreviations.html I have never been to Walberswick, but I have travelled to a few places relatively nearby, from Canterbury to Margate and found the area super charming (I lived in the UK for 5 years, 2009-2013). Good luck with your TWW & TTC, post IUD.
Ah, my husband (also American) and I met in Oxford (he was doing a study abroad) so we are well familiar with the city. I'm in Boston now (also for a PhD).
