I bled 3 days before my period but it was on and off and it was for 5ish days during this time I had no cramps whatsoever (due to how light it got I don't know if to class it as 3/4/5 days) was then due on my period on the 24/08/2016 but it never came or I didn't continue bleeding for that matter. My moods have been all over the place. I cry about the most ridiculous things I get nausea waves as night time. Extremely sensitive and I get a metallic/bloody taste in the back of my throat. My 4 year old has become VERY clingy as if he can sense something is different or changing. The bottom on my abdomen is quite firm. Every morning when I wake up my lower abdomen feels tight. This hasn't happened before. My first preglance was so swift I can't compare it as I was also so young I didn't know what to look out for or what to class as "different" or "weird". Pregnancy tests have came up negative. Although I've read up to wait until I am a full week late and then go to the doctors.
