So, I got done with some masturbation and after the big o usually I'm swelled shut, to the point where I can't even put a finger in. So for some reason I tried after some rough fingering going on and there was blood on my finger everyone I took it out (3 times). Is this a jump start on my period or did I scratch myself or what? My period is irregular so I don't know if it's coming soon, but I'm on cycle day 22. Thanks!
