I’m 8 weeks

So I am 8 weeks pregnant as of Sunday. But I had to ask for some advice ever since my six week mark I have not been able to sleep because of nasal congestion. First I thought I had a cold but I have no other symptoms and it only happens right when I’m trying to sleep. I’ve tried blowing my nose but I have nothing in my nose that blocks my breathing and I’ve tried Vicks under my nose. Does anyone have any advice for this? And did you go through this?
