I totally agree with Victoria!!
Congrats on the pregnancy, and try not to read too much into symptoms. A LOT of women have symptoms, but then again A LOT of us have had none at all, then again SEVERAL of us have them some days and not others, and very few of us have the same symptoms. I agree that you should attempt to quite smoking... or continue to cut down, and try not to stress (I know its easier said than done, but its not good for you or the baby), if you don't have any bleeding (although lots of women do have some bleeding in pregnancy and go on to have perfectly healthy babies) or REALLY BAD cramping you are probably just fine. Good Luck hun! And let us know how your doing. When is your first OB appointment??
First, congratulations! Second, call your OB and make an appointment. Third, try to stop smoking completely, but if you can't, cut down until you can stop. You can get some prenatal vitamins over the counter until your OB prescribes some for you. Pregnancy symptoms come and go, just be thankful on the days they go. :) Congrats again and heres to a happy and healthy nine months!
