I have had 6-8/10 lower abdominal pain for over 72 hours. This pain is similar to menstrual cramps but its more painful on the left side than the right. The pain is crampy and comes and goes but when its at its worst it feels like stabbing. I have already previously had an appendicitis 3 years ago. I had some spotting 2 days ago and since then I've had no bleeding at all but the pain is still there. I am 20 years old and female and this has never happened to me before.
