hi. My expected period was May 23. I woke up on the morning of May 20 bleeding. I bled for 3 days then stopped. The flow was mild not heavy at all. No cramps whatsoever. On the 23rd i spotted a little throughout the day and became very nauseated and the nausea has stayed with me all day every day ever since. My stomach feels bloated and i have let gas out. no pain anywhere. yesterday i was at work work and i lifted a few heavy boxes and when i went to the restroom i noticed i spotted just a little. and i m urinating more frequently than normal. any ideas on whats going on. Pregnancy test showed negative result as of last night
