Okay. I'm on birth control and I took it 2 months straight so I didn't have a period when I was suppose to ( my intentions). Right now I'm off the pill so I can have it, and today I was having it. But the thing is I always use pads, and so today I tried a tampon for the first time today. I took it out a few hours ago and haven't bleed since. I don't know what's going on... so some one help?
