ive missed my period!

What about October?

Did you have sex during Sept or Oct?

"What about October?"

In my head I have an image of someone reading this and having a sudden lightbulb moment.

If not a baby most likely the reason is too low of body weight. Are you anorexic?

You need to take a pregnancy test and/or see a doctor very soon.

if it's any consolation, you might be missing your period, but you've found your exclamation point.

Hi!
Missed or delayed periods is not a rare case. First of all make sure you are not pregnant. As about the other causes of the delay they can be very different. For example: bad diet, stress, excessive physical activity, hormonal imbalance or some health disorders (e.g. thyroid problems). By the way you haven't indicate your age. If you are a young girl and your periods have started just a few months ago, then do not worry it is a normal condition related to the hormonal system that requires some time for regulation.

Yes, and when you go to get your thyroid levels checked make sure you get a babysitter for the 7 month old you have.
