I'm really concerned because I'm 3 days late on my period and that never happens to me. Normally, Id be getting these cramps, headaches, backaches, and mood swings right before my period starts, but even with all these symptoms, there's still nothing. I was supposed to get it on Friday, and now its Monday. I did something on Wednesday thats freaking me out a bitI masturbated after having sperm on my fingers, but I did wipe it off with tissue before that, and it wasn't immediate. Plus, on Saturday, I pushed myself really hard during a workout and ended up feeling dizzy and nauseous. Could either of these things be affecting my period, or is something else going on? I'm starting to panic here and would love some insight.
