Is this normal? (period question-10 points!)?

I already asked this question but only got one answer so I would like other people opinions. Alright, so about a year ago I got my period two times. Then it just stopped until four days ago and I got it again. It only lasted for two days and I haven't had it today or yesterday. After eating today I have this TERRIBLE cramp on my left side. I haven't bled for two days now though..I don't know why I'd have a cramp now. I've never had these cramps before. Also, the blood is sort of brownish..it's not red. I took some Pepto Bismol and that seemed to help. I also read that your period can stop due to stress. I am a VERY stressed out person. I have terrible anxiety and worry about everything. Is this normal?
