I'm glad yo asked this question. I was kind of wondering about it myself.
My CM isn't great, but it's pretty good and I wouldn't want to mess it up. Making it even better on the other hand would be just fine with me.
I don't have great CM but the DHEA didn't make it any worse, nor any better.
i didn't have great CM to begin with, but i actually noticed a bit more when taking the DHEA. However, I was told that lack of CM can be a real problem when TTC, so we used pre-seed lubricant to add more. it worked!!!
G/L, I was hesitant too, to take the DHEA, but I figured, i'd try it for three months and see what happened. I hope you get that bfp!!!
I have read quite a few incidents of DHEA creating more CM. I have a ton this month and am taking both DHEA & EPO. I have taken EPO before and never noticed a difference..but I sure have this month. Don't know if it's the DHEA or not, but it certainly hasn't dried me up.
