So overwhelmed!

Ma
I found out yesterday that I was pregnant! EDD is November 18th. I'm no longer with the father of the child. Conveniently we broke up a day after the day my baby was convinced. He is being very supportive though so as of right now there are no problems there. But I'm so confused and lost and really, really scared! I didn't know I was pregnant so I didn't make choices that would positively impact my baby such as drinking, so I'm really worried about that and if I've done too much damage already. This is a birth control baby. For someone who took their BC religiously, this is a huge shock! I just don't know what to expect and what I should and shouldn't do. My first appointment is tomorrow, but not with the ob gyn. That probably won't be until next week. I would just appreciate any and all advice on what to do during a pregnacy since I've never experienced this before! Though the situation isn't ideal, I'm trying very hard to be positive about the situation!
