Relocating from LA to London during pregnancy

Hi everyone. I wanted to get some insight on what people on my same timeline think on this... 
Before we found out we were pregnant my husband got a huge promotion which came with a relocation for both of us to London for 6mo-12mo (we have lived abroad in Europe, South America and travel all the time, so we were very excited about this and used to living abroad) Now that I'm 5wk5days it puts our move right at the 24 week mark with me delivering and living for the first few months abroad. 
It's by no means permanent which makes me feel better but I am still weighing the pros and cons. My husband is so considerate and he says the move is COMPLETELY up to me but it could be cool/fun and plus at that time babies are so immobile it would only be a month or two we are there before we come back home and are with family and friends. It's a huge job opportunity so I don't want to just dismiss it. Anyway looking for some other insight from people who are in the same timeline as me.  Thanks!!
