2 days ago, i went to pee and i noticed when i wiped my pee was pinkish, i thought this was my period coming 4 days sooner than expected, but i haven't seen anymore blood after that, i still did not get my period, this worries me also because a few days before this incident, i had a very sharp cramp in my abdomen that took my breath away and i could not move for those few seconds. am i dying of some desease?
