Okay so I was 1 week late for my period. I took 2 pregnancy tests because i was worried and thankfully both came out negative. Today I finally got my period, but it was different. I usually get them right when I wake up and today I got it at night. And it is extremely painful. I normally get really bad cramps but this ones worse than normal. Is it just because I am a week late that its more severe? Should I be really concerned and go to a doctor? Any advice would be appreciated! Thank you.
