Cold symptoms

Ever since I’ve been around 8 weeks pregnant, I have had ‘cold’ feelings. Every morning I wake up my nose is clogged and I can’t breathe out of it until I blow it, which causes some random nose bleeds, i have to spit up flem (sometimes has blood in it but I’m thinking from my nose bleeds), and I have a hard time breathing, like I’m out of breath but I don’t do anything?, sore chest/sternum, cold air feeling when I breathe in sometimes, Headaches, Fast heart rate & heart palpitations.. I’m now 15 weeks and this still happens. Has any other moms experienced this? Apparently cold symptoms are common in early pregnancy, but want some other moms feedback 🙂
