I'm supposed to be on my third fertile day, but I'm having what seems like a light period. It's too consistent to be spotting, but too light (and too early in the month) to be an actual period. My last day of the last one was March 5. So what would cause this. Stupid PPO (which is all that's available in my area) takes 3 weeks or more for a doctor's appointment. There is a women's clinic an hour from here, but I don't want to take time from work and make that trip for nothing. Right now I'm not concerned. I'm not in any pain and I don't feel sick. I guess I'm just wondering if and why this happens.
