Headaches. My head is going to explode.

Tonicia • Wife. 29. 1st baby due Oct ‘18.

I’ve been really sick so far starting at week 7. I’m in week 12 now and still no slowing. My head is killing me for the past 3 days and I don’t want to take too much Tylenol. I rub peppermint oil on my head which always helps but is temporary relief. I’ve slept with ice packs on my head for hours. I finally just drank a soda (I was told the caffeine helps). It did actually help a little, but the headache is still there. Anyone have any relief remedies?
