Can anyone help?

I am 30 weeks and I have had a headache for 2 days now Tylenol hasn't worked and not I feel weak and dizzy. I told my doctor today and she told me to drink a little caffeine which I did but nothing has changed. I get frustrated because they never take my concerns seriously but I feel really crappy I didn't feel like this through my entire pregnancy so this is new I have also been getting nosebleeds 2 times a week sometimes even 3. They told me those are normal pregnancy symptoms but I'm not so sure. They also found protein in my urine which they made me do a 24 hour urine test and blood work that has been sent to the lab and I have to wait to hear back. Has anyone experienced this before.
