Is it something i should worry about?

so anyways last night i stayed up till around 12 my usual bedtime in bed watching glee on my ipad in bed. Then i feel asleep and woke up half an hour later bc i was so hot… Like literally it was almost like a hot flash. And nothing would work i stripped 3 layers going from polyester pajamas to cotton to literally SHORTS AND NO SHIRT ON and i was still hot and the fan was on. But then this morning im back to ormal. A few hours ago i was watching supergirl (AMAZING SHOW BTW) and out of no where i get this nosebleed that i only realize after i look at my tissue and see blood. And it was crazy even if it was one drip at a time it was ongoing and continuous. Anyways the temp at that time was 68 degrees and its winter so thats not really that warm… And it was also 68 in my house when i was falling asleep… Im a 13 yr old boy btw
