Sounds like it, as progesterone is usually the culprit and it rises before a period. Plus if you're on HRT it's more progesterone again isn't it. Blummin hormones they rule our life. I know how awful anxiety is I wrote the book! It's half the battle when you know what could be causing it though. Age old remedy, good diet and exercise should help and try and stay in the moment there is some great relaxing things on You Tube if you can access it. I'm into Jason Stephenson at the moment, calming affirmations etc. Plus ELT it's tapping on the body, it distracts from the anxiety symptoms. I hope this helps you Hun, take care.
