I'm so so confused about my body right now. need help. or advice.

So I have had light bleeding since Sunday not a normal AF for me. Before that I have major pregnancy symptoms. Bleeding was bright red but light. I passed a very very small tissue. No cramps. All test were negative. 
Now I  have brown/pinkish, went to check my cervix because it's be high and soft. After I checked it the bleeding went from brown pink to red again but it was a little not enough to fill a panty liner. And I'm sure it back to brown/pinkish again. Just so so confused on what's happening to my body. 
I have never had this light of a period before. After I stopped breastfeeding my son they have been the same heavy and dark red. Idk I'm gonna wait a week or so to see what happening. Just confused. 
Anyone have a light period and then found out they were pregnant. And tested to early on the blood and home with negative. But was actually pregnant. 
Confused that's all.
