Good day, I have a question about my period, last January 2017, I had an overtime duty. That's why I understand why I only have 1 day period and it was very little, maybe it's because of stress. By February, no period at all, and by March, I only have little, just like January. I drunk beer last January as what they had told me and nothings happened. I don't know what to do now. I'm single & there's no reason to get pregnant. This is my first time because the last menstruation was all normal(3 days every month). 

I will wait for your advises before I will go to doctor, Thank u and God Bless!
