So my period has skipped a month. I had my last period October 26th and I missed a whole month and now it's dec 20th and I have my period but it hurts more and there's chunks of tissue and it's painful. I was going to take a pregnancy test in a week but my period is here now. First the period started small and a little and now there's chinks of stuff coming out and I've been in pain for a week now. I've never had a period like this one? What's happening? I don't know if it's spotting or a period.
