Paranoid!

I need consoling. Basically I've been on Yazmin for about 6 years, I came off them a few months ago, they gave me regular period patterns but now they don't suit me anymore so we're using condoms now and I can't remember what my periods were like before the pill. This month my period came 2 days late and it's very light more like dark red spotting I had my usual pms symptoms. I've taken pregnancy tests and they're all negative and I don't think I'm pregnant. I haven't taken care of myself recently my alcohol intake has increased (my anxiety and depression is back in full swing)and I've been eating junk. I just need to know if anyone has had a similar problem or how I can take care of myself a bit better...
