Pulmonary Embolism?

I had a Pulmonary embolism 2 years ago. I am 24/f, in descent health, didn't use birthcontrol pills/injections/adhesives, didn't go on a long trip (car or plane) so my doctor never gave me a reason why I had such a life threatening embolism. A few days before I had it though, I was in a single car accident in which I
hit my nose on the steering wheel and it fractured along the middle of my nose. I didn't pass out, I was wearing my seatbelt, didn't hit anything but my head on the steering wheel, felt no pain in my chest immediately or even the next day. So I don't think a broken nose could've caused it.
I also am pondering if I could have some kind of blood clotting disorder that caused it. When I went through the PE, it was tiring, painful, I couldn't even take care of my daughter, and I could've died, so I'm scared that if I have another one it could kill me this time. Anyone have any ideas what could cause this kind of PE? Thank you.
PS Anyone go through something similar?

It doesn't seem unlikely that the nose fracture couldn't have had something to do with it, but I would think that the embolism would have gone to the brain from the nose.

Typically embolisms can happen while on birth control because it tends to thicken the blood. Since you weren't on BC, has there been any family history?

It seems strange to me that your Doctor would be so evasive as to why it happened. I would see a specialist and take your records to them and see what questions you can get answered. There is always aspirin therapy to keep the blood thinned out. I hear it's the best thing ever created and to take a baby aspirin once a day for ultimate health.

Of course you want to be under a Doctors care and advice before doing that. But definitely find someone more experienced than your current Doctor.

GO TO THE DOCTOR

Hey, you forgot smoking and obesity as risk factors as well as recent surgeries. I wouldn't completely rule out the car accident (humans don't know everything about PEs yet).

You can ask your doctor to check you for blood clotting disorders. You should ask your doctor to check you if you have another PE or leg clot, your family members have had clots in the legs / PE, or if you have female family members who have had spontaneous abortions.

Good Luck. I know it's scary but you will likely do fine.
