Sinus Medication Solution

I’m not being nasty. It is nasty to me. actually. I’ve been having this not sure what is is cold or sinus infection for 5 days now. I don’t want to take medicine because I am pregnant. My nose runs alot and is stomped up. Yesterday I kept blowing my nose and snot came from my eyes and nose. I could feel me blowing out of my eyes. Whats up with this?

I’m sick with a cold so i went to the doctor to get Amoxicillin, also with sinus relief nasil spray. After taking Amoxicillin, and the spray, and hour went by and i was vomiting on going for 10 hours, even when there was nothing left. Then I started tasting a bitter flavor when i Vomited, maybe the nasil spray? Also, i got this red dot rash all over my face.

What do the red dots mean and why did i get so sick with the two medicines with ongoing vomit every 10 mins. Does Amoxicillin (Cold medicine) have that side affect usually?
also does it depend what kind you take?
wait so i should stop taking, what happens if i dont go back to a doctor without taking amoxicillin? will vomiting still continue unless alergy is cured?
also the red dots on my face are vibrating over and over. Is that a sign too?

I was tested negative twice in two months and now i can feel my sinus infection coming back somehow i had a little blood in my mucus after sniffling. and my nasal cavity is dry and so is the back of my mouth when i woke up this morning. Is this a sign of the acute hiv illness?
