Headaches, sinuses, colds, nose bleeds while pregnant.

Aby
So I'm 12 weeks and 4 days, I have suffered quite frequent tension headaches through out the last couple weeks which I actually got quite often before being pregnant, usually a lie down subsides them and I will sleep them off. However twice in the last month I have had the same kind of tension headache which I haven't experienced before, it's a severe tension headaches mixed with a mild (even mild is extremely painful) migraine style headache always towards the left side of my head, behind my eyebrow and at my temple. It starts in the afternoon and get progressively worse that I can't even stand up by bed time it feels as if my whole head is completely swollen and throbbing, and the next morning it's not gone it turns less into a tension headache and more into a migraine! So I had that headache yesterday and was actually pretty successful at getting rid of the second headache this morning. Another thing I have been expediting for a few weeks is runny nose, runny eyes and the feeling of an onset of absorbent broad however I don't feel sick like I have a cold so I was thinking it could be allergies (although it's feburary and iv never suffered with allergies my whole entire life) or sinus issues? Also this morning I blew my nose and it was bloody, I rarely get bloody noses but I was concerned since I just had this terrible headache! I don't know if it's all connected or if it's just pregnancy related or what! Any experience!?
