When I included MSM in my regimen, I noticed few weeks later that my monthly cycle changed from 27 days to 30 and even worse now 34 days!! I also noticed that it messed up my ovulation cycle too
. If you are planning to get pregnant, I suggest you stop taking msm about 3 months before you start trying. Also if you use the "safe period" type of contraceptive and you are taking MSM, you better be careful! I just felt like sharing.
