Not much chance of us being able to have a baby is there? :-(?

There is ALWAYS a chance. Never give up hope. Although your boyfriend smoking pot does bring your chances down, there are thousands if not millions of people that can conceive even while taking stronger drugs. Either way if you want to have a better chance of conceiving ask your boyfriend to cut down on his pot smoking and drug usage. I'm not particularly saying that that's going to do the trick but it can help. Other things you can do is talk to your ob/gyn and ask them what you can do to increase your chances like taking prenatals or even fertility drugs (although it is my understanding that they won't give you fertility drugs until after you've tried for at least a year) I Wish you the best of luck and keep me posted k 8-D
