Hey there, I was a couple of days late for my period, and had taken an early test about 3 or 4 days before my expected period, only to have it negative. We are not trying for a baby, but I had a feeling. Yesterday my period started so naturally, I came to the conclusion I'm not. However, in the middle of the night I had to rush to the bathroom, thinking my tampon was full and I was leaking, only to find the tampon was only about half full and my panties were soaked with a water-like substance. Could this be amniotic fluid and that I am having a miscarriage?
