I just got spotting this morning (CD19 with no sign of O). I started taking DHEA this cycle also as I heard it builds up the uterine lining. I also just got reading that it can cause irregular periods.... Not sure this is a period yet but I think I need to drop the DHEA, there's information that if you have uterine fibroids (you may not know if you have them) it can make the fibroids worse. Think I should stop taking DHEA. I honestly don't even know if my uturus needs building up. I could be doing damage. Plus it says DHEA can cause hair loss 8-z. Guess it is a good think I have forgotten to take it the last few days. Oy!
