Aww hun, i suggest you go to a doctor and get you and bub checked out asap.
I know from what you said your reluctant to see a doctor. But if you explain that your having problems, then i'm sure they will understand.
Your not the only pregnant woman to slip up while pregnant. I had a particularly horrible night a few weeks ago, like really horrible. I've had a history of really bad depression and anxiety problems.
I had that same old feeling i used to get when i was at my worst. And i had a joint.
I've been freaking out just like you. I just needed something.
I'm not proud of myself, not at all. I hate myself for it.
But you need to go and see a doctor, to put your mind at rest and make sure bub is ok.
Please take care of yourself honey.
