Are you using plain Gelatin? (not flavored Jello). Use Perrier Sparkling water. Mix it really fast in a glass and drink down. It clumps. Drink it all. Suck on lemons or squeeze lemons in water and drink. If you are desperate enough also, add three teaspoons of apple cider vinegar in a half glass of water and drink. Take four over the counter ibuprofens and it will definitely stop. One month I had to do all of those and it went away for two days. And no when the next month come around it doesn't come back harder or worse. I've been alternating these methods for months and they absolutely work. Like I said one particular month I had to do all of the above but it was worth it. It wasn't bad, nasty or horrible. I'm a healthy woman so none of it damaged anything. Trust me.
Dissolving 1 packet of gelatin (jello works too) in a glass of water or fruit juice is effective in stopping your period for a few hours..it worked for me..
I did a combo at some point (gelatin drink in the morning, drunk squeezed lemons in the afternoon, and drunk 3 glasses of ginger concoction at night -- boil ginger for a few minutes, add honey and drink while warm)..it eventually stopped my period for 1 day..I didn't even experience spotting..
try taking a combo 1-2 days when you know your period is about to start or on the very first day of your period..
by combo, I mean (drinking lemon, gelatin and ginger)..
good luck
