It is very hard to discern ovulation symptoms and early preg symptoms. All the thingds you felt does not mean your preg. Sounds like you stressed yourself out worriyng about having a period that is why it was so light. Trust me I am preg. now with my third child. With my first I wanted one so bad I went through the very same thing but it is not a miscarriage maybe implantation bleeding. Besides the grass is always greener....
