Overdose/ Self-Poisoning Question - OD/periods

[~invisible~girl~]

So my period should have started like two weeks ago, and since it's never been off by more than a couple days since I was 13 (I'm now 21), that's kind of weird... Considering I haven't had sex, or any form of sexual contact whatsoever, the chances I could be pregnant are approximately zero, so it's more just a matter of if something's wrong or whatever... Anyway, I took an overdose a little over three weeks ago, and I'm wondering if it could be related to that. In retrospect it was a fairly dangerous OD (although mainly because I apparently threw up in my sleep), but as far as I can tell, I'm otherwise fine... So I'm wondering if it's just like the stress on my body messed up my menstrual cycle for the month or whatever, or if it could be a sign that something's wrong that I might need to worry about or something. So, um, should I be worried?

The OD could be a cause of it as anything that upsets your body can alter your menstrual cycle a bit/ delay your periods. Stress can also affect it. As well as this, any change in liefstyle/diet/weight can affect them. As it's only 2weeks late I'd just leave it for now but if, in a couple of months, you still haven't come on I'd get it looked at. If, in the meantime, you get additional problems I'd get it looked at
