Brown discharge?

🙃

I tested positive on Sunday (Easter) and also tested positive Monday morning as well. Tested again Monday night and it was negative (slightly lighter than control line) now it’s Tuesday and it’s still pretty dark but negative. Yesterday I started having brown discharge and slight cramps? It this due to ovulation or? Im still having brown discharge when I wipe but it’s more than yesterday... felt constipated yesterday morning and felt a little nauseous but went away with in an hour or less. Still kind of constipated today as well....
