Hi there. I have been having period like cramps ever since my period ended over 2 weeks ago. It's like a dull period pain, sometimes along with stabbing pains on the right side of my abdomen. It has been going on for around 2 weeks, I thought I was pregnant as my period this month was 3 weeks late, but I did 2 home pregnancy tests and they were negative. But the pain is still there. The pain has happened before. It all started at around May 2017.
