I had headaches when I was 18 weeks too. Now at 21 weeks I no longer have them. They stopped in the middle of week 20.
I've had constant headaches since about 13 weeks. Am 17 weeks now and haven't gone away yet.
Hopefully mine stop around the same time yours did! Thank you :-)
My dr told me to eat more eggs, cheese, peanut butter, and yogurt she said that your body needs more protein
Yes! I've had headaches like crazy and this is my second pregnancy as well. I've been going to get accupuncture which usually helps for a few days!
