Confused, worried... and everything else

I don't know exactly where to start. It's hasn't even been 24 hours since I found out the heartbreaking but beyond excitment news that I'm pregnant. Heartbreaking? I found out after having 2 margaritas, a month of drinking during the weekend, moving, boyfriend hasn't had a job in a month, that I am having a baby. I cried, he cried (my boyfriend), I kept crying.... We found out at my best friends house with her husband (who my boyfriend used to live with before I even came in the picture) and one of their other roommates... I'm only 19, my boyfriend lost his job due to depression of his fathers death and he would miss work a lot because he hated his job with a passion. I work where insurance isn't provided... My mother past away so I wouldn't have her support, and well my dad. Is still part of my life, even though we do share our differences, but I'm still scared to tell him the news. Scared CRAPLESS. I have mixed emotions; why? Hell, I'm pregnant for one--but the things I've done over the past month, scare me to death about my babys health. I have drank, tanned, I don't smoke, I don't do drugs... But being this early into the pregnancy, am I still okay? Is the baby still okay? I will be going into this without insurance for the first couple of months I'm sure and maybe a little bit longer. I don't know how that's going to effect me; honestly I don't know anything! But I told my boyfriend, that I want to get tested first. And he threw a hissy fit, because he was 100% sure that he didn't have anything. I'm unaware of a lot of women things. I was young when my mother past away, so I didn't get to speak her to about women problems. I grew up with five brothers and a father that's strict. To begin with my problems. I discharged, a lot.. The smell, was strong, yellow, and a mess on my underwear. I haven't noticed much since, but the smell is a little strong still this is before I was pregnant.. What does this mean? I'm having cramps on the left and right side below my ribs, I don't know what this means either. I haven't had the morning sickness and smells haven't bothered me except smoke (which has ALWAYS bothered me). Support: I have my best friend, her husband (who's my boss), my boyfriends mom, stepdad, and my boyfriends two friends. I haven't told anyone beyond special to me yet the news. I'm still shocked as hell, but like I said before, scared of what my dad is going to say and what he'll do. My brothers, well they have either been in the same situation as me, or a little bit worse. I totally have my boyfriends support -- he's 15 years older then me, wants to be a father but we both planned on doing things the right way. Guess that plan went down the drain. We're scared--and I would LOVE to have your support and your insight, rather you already have a baby or is going through the experiance with me. I'm looking for friends to keep me grounded because I'm not sure if I'm going to have friends after the news get spilled -- since they all are young but were not ever on the same maturity level as I. If you'd like to know anything else, please don't be scared to ask. And just in case, I AM keeping the baby.
