Period gone awol after starting running

[dontfluffthefluffer]

Any ideas?

Started c25k at the start of April. Period was due to come along in the first week or so of the month but nothing.

Thought maybe my body was protesting and this month would reset itself.

Now at the end of c25k and nothing still.

Is this something that just happens? I've never experienced it before when I've run previously.

Not limiting food (though I seriously should be!).

Pregnant?
How much do you run? Would someone say you are overdoing it?

Definitely no chance of being pregnant. I haven't been overdoing it, 3/4 times a week. The first few weeks were quite easy so did 4 runs, now they've got longer have stuck to 3 times a week.

Will go to the docs, I just wondered if anyone else had experienced this.

sounds like coincidence
