I did pretty much the same thing with my first born. I was so scared too when I found out I was pregnant. My doctor assured me that the baby should be fine since it was still so early but to just make sure I didn't drink anymore after that. I still worried, of course, but made sure I was real healthy after that. My son has always been perfectly healthy and is now a strapping, handsome 21 year old who just got his associates degree and is just too darn smart for his own good, lol. I hope that puts your mind at ease a bit.
Do make sure you don't drink or smoke anymore because it will affect the baby if you continue doing it the rest of your pregnancy. I know it's hard to quit but try sucking on hard candy or lollipops (in place of smoking).
It sounds like you're about 4 to 5 weeks pregnant or so. Do make an appointment with an ob doctor and get on your prenatal vitamins as soon as you can and start trying to be as healthy as you can for your little one! And congratulations! :)
yeah as long as you stop from here on out, your placenta hasn't developed yet so I wouldn't worry too much. Just tell your OB like mamaofonetrying42 said and keep clean and you should be fine. :)
So if your LMP was 10-31, then you would be like 5w5days. Many women do what you have done....The good thing is that you now know and can start protecting your lil bean. I am sure everything is fine, just let your Ob know....Have a great 9months!
