I'm 23, and I've been dealing with this too for a year and nine months. I've been bleeding since September 2015. The clots are smaller now, but they're still big, and pass several times a day. The bleeding has made me anemic and I take iron supplements. The iron does keep me from fainting, but I'm still exhausted all the time, my back hurts, and my "insides" feel raw from all the bleeding. Don't even get me started on the cramps.
For me, the blood dam opens when I eat meat, dairy, and processed foods and it goes on until it's completely out of my system, the heavy clots that is. I also started bleeding like this after my weight balloned. All this menstrual irregularity started after my mom passed. The greif wrecked havoc on my hormones, which wrecked my body. Didn't even know that could happened. At first my period stopped entirely for two years, and now it's back and has never stopped.
I'm getting so tired of this. I'm fed up! It's like a bleeding curse or something. I've been losing weight, and wonder if I lose enough will it end all this? Even if it means being underweight? I'm so sick of bleeding. I'm getting very desperate. I've read through this thread and saw some people talking about Vitex and Inositol Powder. I'll give that a try before I take more drastic measures. I have no insurance, so I'll have to pray and figure the rest out. I hope we all find not only answers, but successful solutions.
