I typically have a 26 day cycle. On the 24th day I started having a light pink/brown discharge that continued off/on for 2 days, as well as some fatigue. Then on the expected day of my period I had moderate bleeding for 3 days. I ve had dull abdominal pain, not typical cramps, and one incident of vomiting and another incident of dizziness/sweating, over the past 3-4 days. Today, I have had a lot of light pink and clear watery discharge. My partner had a vasectomy a little over a year ago, so thinking pregnancy is unlikely. Thoughts?
