Worried it may be CSF leak..?

It could be all from being pregnant, but idk i'm just beginning to really worry! It doesn't happen every time, but most of the time when I bend over my nose with drip a very thin, watery fluid. I do not get the headaches tho.. I've heard with csf, headaches are extremely bad. The only thing I get is what seems like pressure in my head when i stand up too fast sometimes i almost black out for a few secs but then my vision returns. I'm guessing this is just from standing too fast. I haven't had any kind of head trauma or any kind of trauma for that matter. The most dramatic thing that has ever happened to me was child birth 10 months ago and yes i gt an epidural, but this leak from my nose has recently started. Some days it leaks some days it doesnt. I'm not sick no sinus problems or ne thing i feel fine but i dnt understand why my nose leaks when i bend over... And why is it no watery... It almost feels like a nosebleed or like when u eat something hot, idk if tht happens to everyone lol, but when i eat something really spicy my nose runs! Does this sound like a possible small csf leak or just nasal mucus...? Just want some answers please.
