Patient: So I’m taking the conception of Microgestin 1/20. Granted tobacco & marijuana can results into health risks I’m curious as to the pregnancy factor. My question is can marijuana increase the chances of pregnancy if while on this pill? I’m taking it regularly, I ‘m just curious; I’ve researched that my partner can cum into me on this contraception if taken regularly but there’s that 1%-2% chance of getting pregnant. But again my question is can marijuana increase that chance?
