Headaches!!

I started getting headaches on Wednesday ): I thought nothing of it since I had no headaches yesterday. This morning I decided to drink chocolate milk and an hour later i started getting light headed and it subsided down to a headache. My headache on Wednesday started after I ate one cookie ): Thursday I made sure I had no sweet junk food and I was fine..

I passed my GD test @ 20 weeks but I’m worried I may have developed it. I’m mentioning it to my doctor when I see him on Tuesday but has this happened to anyone??
