I did. But all it was was a spot (about the size of a penny) on my underwear about a week before I was supposed to get AF and that's it. It wasn't persistent or anything. I actually thought it was pretty weird because
I NEVER bleed early or spot at all.
It sounds to me like you may be spotting before AF since it happened after your expected start date? Unless you ovulated later than normal... Are your cycles pretty regular?
