So the last time I had intercourse was Friday Dec. 12th and I didnt start my ovulation week until Sunday Dec. 14th-Dec 21st. But the 22nd I started having brown spotting. It continued for 7days exactly. And Christmas day I took an ept and it was negative. That Friday I went into urgent care to see if it was something to worry about. They had me take another pregnancy test and it came out negative again. And they say it can me an a bunch of things. But I was also still spotting till that Saturday night. I've been looking up on line and some places it says implantation bleeding or it can be a health concern. But what kind of health concern? Im 25 years old and scared out of my witts. What else could it be? I'd rather be pregnant then thinking its a health issue. My period isn't due till January 1st. And I have a doctors appointment set up on monday. So im hoping its not anything to bad but still want some other opinions and ideas so I can prepare myself.
