I have suffered from unbearable pain during my periods and experienced very strong PMS symptoms. I was shocked to learn that it was indeed PMS (and endometriosis..). Abdominal pain on the first day of my period is still there, but milder—I only need one painkiller instead of three, which is already an improvement.

Nettle has genuinely changed my life. I have just finished my fourth cycle of trying it and my symptoms were reduced to about 10%. It felt like very mild PMS compared to the severe, life threatening PMDD I usually suffer with.
