around 3 weeks ago i was getting headaches on the left side of my head constantly for a week then for the past 4 weeks I’ve experienced light abdominal cramps and stomach pain and what feels like a scraping feeling in my lower left stomach. I feel nauseous when i eat and Ive had some indigestion. I cut out red meat from my diet around 5 months ago & i cut out chicken too last month. I have to admit ive been skipping meals every few days and eating junk food. I also take the combined birth control pill but no other medications. What could this be? I’ve considered pregnancy too but i take my pill on time and ive had my withdrawal bleed.
