Can hemophilia develop suddenly?

At risk of sounding like a hypochondriac, I can’t decide whether or not this warrants a visit with a doctor.
Twice this week I have had very minor cuts and what seemed like excessive bleeding. Last night I cut my shin, not at all deep and very small, and it bled excessively for almost two hours despite the fact that I was consistently applying pressure. Earlier this week it wasn’t even a cut, but a small scratch that would not stop bleeding.
I know that hemophilia is rare, but also hereditary and my grandfather had severe hemophilia. Is it possible to develop hemophilia later in life?
I do not take aspirin or warfarin or any similar medications, so it isn’t a simple explanation like that. Could it be just a fluke thing that I had these two minor injuries that turned out to be bleeders, or should I be worried? I am a little unsure about going to the doctor and saying “I cut myself and it bled a lot.” I’m just not sure if this is something that should concern me, or if I’m fretting over nothing. I already know that “see a doctor” is the standard and safe response to medical questions, but I’d really appreciate it if it could be understood that I am not looking for a diagnosis. Just opinions. Thanks.
