BC but No condoms

Jess • Jessica 25 years old with a 3 year old son
Ok I've been on BC for over 3 months now. October 28 till November 9th I had light spotting and I have not had a Period as of yet. Took two test to be sure but both say negative. My stomach is so tender to touch and just feels like butterfiles. Never done this before so just trying to see what y'all think.
