I am trying to get pregnant. I am healthy, no problems. I have had a cold for a week and took lots of cough and cold medicine. I have the odd alcoholic beverage and like to smoke marijuana on occasion.. My period is due in a few days, but it s never regular so I m not concerned. If I conceived in the past couple weeks, would there be any harm on the baby? Once I find out I am pregnant I won t be partaking in any of the above, but I thought I would have fun trying.
