Here's a thought, maybe it is not estrogen related. Perhaps, your water intake is not enough and your body is just trying to retain water for survival reasons. Check your sodium too, that also retains water if it is too high.
I say this b/c I really watched my sodium and upped my water to 1.5gal/day, and my face thinned out.
Of course I did cardio and a low-carb diet as well, which probably had the most to do with it. Try this approach before drugs are used. BTW, I don't think Clen is going to do anything for you.
