So I've been smoking weed now for the last two month every night non stop. I'm trying to conceive yes I know I should smoke during this time. I recently stopped smoking 5 days ago my period was suppose to come 4 days ago and it's not here yet! Am I pregnant or is this the the weed effects to my period. Please help. It's still to soon to test. I have no side effects. Although I did start to get a cold 4 days ago!
