Did anyone have an increase in anxiety during early pregnancy?

So this is the deal. I am supposed to start tomorrow. I am having a major increase in my anxiety. I can't describe it, but if you have anxiety, you know the feeling of dread or being scared. I am not dreading being pregnant, I just have this feeling that the bottom is about to drop or that something bad is going to happen. The anxiety started getting really bad about a week ago and I don't know what else could cause it. I have been able to keep my anxiety under control for about 2 years now and I don't know what could be causing it to flare up so significantly here lately. I am happy. I have a good life and things seem to be going well, so why is my anxiety kicking my butt? If you have any ideas, please let me know. I would also like to know if anyone with anxiety had an increase in anxiety symptoms during early pregnancy? Thank you
