I took a pregnancy test on Monday and it was negative, although now I am thinking it was just faint. I had a pelvic ultrasound done on Tuesday (3 days after AF was due) because my monthlies have been off the last three months and it came back normal. No sign of pregnancy or abnormalities. I've had very light intermittent cramping since.

And then I took 2 pregnancy tests on Thursday and they were positive. Is it possible that it was just to early to see on the ultrasound???

I am beginning to wonder if my "off periods" were actually chemical pregnancies. I am feeling pretty anxious. Any thoughts?
