I have worked for a number of airlines and I have never known them to think a crew member to be dodgy when it comes to pregnancy least of all because of a potential lawsuit. The environment we work in is harsh so ground yourself ASAP! your entitled to! Make sure you communicate by email or written letter to your managers about your situation. I KNOW they would not question it.. they wouldn't dare. Your also entitled to your Hen Do but would avoid posting pics of you "tipsy" in Blackpool / Brighton / London on any social network site. It WILL get back to your company. I would suggest you re-asses how desperate you are for kids.. hen do might not be a good choice then , but that is just my humble opinion.
But good luck all the same
