I am having pregnancy scares. From fatigue to fainting spells, heartburn, to lower abdomen pain. I'm scared in all honesty and I hate doctors. I know I should go in but I'm afraid. I was against getting my tubes clamped in the first place(got to love mom's) but now this. I'm only a week late. But my periods are always on schedule. Please help am I just being paranoid. I mean my tubes are clamped how can this be and it was done 3yrs ago!
