Middle of the night nose bleeds

Anyone else experiencing these and have a better understanding as to why?

I woke up to my nose feeling like I just inhaled water (that awful burning feeling) at about 2:00 am. So I sat up and felt something run down my face. I thought it was just snot so I wiped it and it kept coming out so I turn my light on and it’s blood. The sinus pressure of it didn’t go away till it clotted and I spit it out. So gross, I know. 🤭 But does anyone have any thoughts on how to prevent this? 🤷🏻‍♀️

I also woke up to swollen legs and ankles. I tell you, pregnancy is super attractive 😒
